Summary: The inverse trig functions (also called arcfunctions) are similar to any other inverse functions: they go from the function value back to the angle (or number). Their ranges are restricted, by definition, because an inverse function must not give multiple answers. Once you understand ...
Usually, when working with trig functions, you'll leave the pi as is and simplify the rest. So your answer will be pi over 2 instead of the 1.57. Example Lesson Summary Additional Activities Finding the Period of Secant and Cosecant In the video lesson, we learned how to find the pe...

Sometimes, you will encounter the composition of trig functions with inverse trig functions. The following are pretty straightforward compositions. Did you suspect the answer was going to be 120o? This problem behaved differently because 120o is outside the range of the arcsin. So use some cautio...

And check the spacing of the solutions in x, it is not pi/2. Oops, I tried it correctly first but then swapped to see if that helped with anything, i put it back in x/y But, i redid the problem and got.. y=0, x = (1/18)pi(4n-1) y=0, x = (1/18)pi(4n+1) Not...
