How to find the equation of a trig graph

the graph has a vertical shift D = − 1. The cosine function attains its maximum value at x = 0. Since this graph has a minimum value at x = 0, it is

Humor is done. It is best. It's really best for common maths which is needed in life. Overall, this is one app I know I will be sticking with for a while, definetly better than the last time i used it which was about a few months ago. Fantastic app, of course this app has its own limitations, but it's still wroth downloading for those who enjoy solving math problems.

But thanks to the creators of this app im saved. It really helps explain the problems, like tracing a plotted curve, if you struggle with algebra, this app is for you. Its a great app especially for me as a public school teacher in Philippines. Excelent math solver. Otherwise, it's amazing. It's a great app.

Determining the equation of a trig function

To find the equation of sine waves given the graph: Find the amplitude which is half the distance between the maximum and minimum. Find the period of the function which is the horizontal distance for the function to repeat. If the
