You will need to change the range of x to 0 to 360 to get the full graph. Several types of graphing paper including logarithmic function, trig, polar and regular graphing paper Numerous output choices, copy equations send graphs and. You can convert using the degrees symbol or the constant d: Note: by default, all trig functions work in radians, not degrees. X and y as functions of t in parametric form You may reference these functions and constants in the same way as the built-in ones. Note that you may also define your own single-variable functions or constants using the Functions and Constants item in the Tools menu. Truncate towards zero (ceiling for x = 0) Perform summation of a sequence or convergent infinite series. Heaviside step function: step(x) = 0, for x 0 Pseudo-random (time-based) number between 0 and arg Greatest integer ( notation not supported) This may be used to prevent overflow when the desired expression is actually something like gamma(x)/e^x. The natural logarithm of the gamma function. The statistical function Γ, defined by the recurrence relation Γ(x+1) = x Γ(x) Synonym for int (greatest integer less than or equal to the argument) Either end may be left open by omitting an operand. 2 m is the start of the domain and n is the end. In all figures A(x) is violet, B(x) is white, C(x) is red and D(x) is. Specify domain exclusive of m and inclusive of nġ parentheses may be nested to any extent, and you can alternate between ( and [ to aid you in balancing your expressions, but the parser will not differentiate between ( and [. First I plotted the 4 functions using Graphmatica. Separate halves of a parametric equation or clauses in a piecewise-defined function Modulo (remainder after integer division)Ībsolute value of expression between "|" characters will be using your laptops with Graphmatica in class to graph equations and functions. Less than or equal, greater than or equal Note that trigonometric functions are not covered in this course. ( Special Characters in the Edit menu) to enter characters that don't appear on your keyboard. You can use the Special Characters tool window Graphmatica supports the following operators, functions, and variables in your equations and user-defined functions. Maksymchuk.Questions? Problems? Please contact me at for additional Remember, here is todays assignment and there is tutoring after school until ten to five with Mr. Therefore sin is "+" and because tangent is a negative value, it cannot be quadrant one because X and Y are both positive. This is a similar question to the one above where we discovered that Theta was in quadrant II because Sin > 0. Here we were just applying signs to values in terms of quadrants and the location of the coordinates. This picture is continued from the picture above. We also talked about calculating cosecant, secant, and cotangent. While we were reviewing the unit circle we found it handy to think in proportional triangles to find the values for sin, cos, tan etc. The class was also introduced to more radian measure and learning to think about what quadrants they apply to. He got us thinking in terms of sinΘ - referring to Y, cosΘ - referring to X, and tanΘ - X/Y. Maksymchuk explained some more about the Unit Circle. The image to the side was also handed out. Then at the end of class we were assigned questions 1-15 on exercise 5 and 1-16 on exercise 6. Then the class was then introduced /reminded of definitions and formulas for them which are on the slides below. Solution: We know that the domain and range of trigonometric function tan x is given by, Domain R - (2n + 1)/2, Range (-, +) Note that the domain is given by the values that x can take, therefore the domains of tan x and 3 tan x are the same. Also the mostly vertical lines are the remaining function tan and cot with tan being the lines bending to the right going from bottom to top and cot being a mirror image of tan. Example 1: Find the domain and range of y 3 tan x. The parabola's are formed by the csc and sec graph's and they touch the greatest value of there corresponding function i.e sec touches sin's greatest values. The image below was handed out in class and has all he functions on the same graph. Next was the actual graphing of the functions on graphmatica and ow it can relate to the unit circle i.e Y=sin(x) is greatest at π/2 on the graph and is positive up until π, which is equivalent to quadrants I and II on the unit circle. Then was a bit Review with the definitions of Domain( the values that x can be) and Range ( the values that y can be) The definition of Asymptote given on the slide below is also very important to know Sec and cot are done like csc meaning sec is (y= 1/cos theta) and cot is (y= 1/tan theta). Next came Reference Curves with a " how-to" lesson in putting the six trig functions into a calculator or other technological device as shown by the image below.
