Trigonometry involves calculating angles and functions of angles, such as the sine, cosine and tangent. Calculators can be handy in finding these functions because they have sin, cos and tan buttons. However, sometimes you won't be allowed to use a calculator on a homework or exam problem or...
The inverse trig functions let us work backwards, and are writtensin−1orarcsin(“arcsine”), and often writtenasinin various programming languages. If our height is 25% of the dome, what’s our angle? Plugging asin(.25) into a calculator gives an angle of 14.5 degrees. Now what about...

Does all of the above seem like quite a bit of trouble to go to for drawing a simple graph? I agree; it is. When working with trig functions, especially those having a phase shift, it may be easier *not* to use the graphing calculator. ...
The Jacobi Elliptic functions are a way to express the amplitudeφ in terms of an elliptic integral u and modulus k. They share many properties with trigonometric functions and can be thought of as trig function generalizations; In limiting cases where the parameter tends to zero, the Jacobi el...

Trig Functions:When you're working with angles, keep in mind many calculators let you select whether to express the answerin degrees or radians. Then, you need to determine whether you enter the angle (check the units) and then sin, cos, tan, etc., or whether you press the sin, cos,...
