I am having trouble solving the the "x" value of a sinusoidal function when given the y value.
Here is a sample question:
d(t) = 2 sin(30t) + 5, solve for t when given the d value of 3 m.
Also another question, T(t) = - 18.9cos30t + 5.8 solve for t when given the T value of 2.
Your help is deeply appreciated
I tried to do the inverse of sine and I got -90, but dividing that by 30 got me the answer of -3 which is not the given answers of 60, 180 and 300.
May you please give more detail as to how I find the appropriate values for w, is it guessing and checking? I am unsure.
Thank you for helping me so far, I greatly appreciate it.
Thank yo so much for your reply, could you please elaborate on this specific aspect:
I am lost as to how you got .,
I am also assuming (if you could please confirm) that k is referring to the cycles?
