mertsj · Answer

The left side is h.  h divided by 7 is h/7

anonymous · Answer

Thats doing the most. Can someone just help me step by step so i can learn step by step & write notes & get off this

mertsj · Answer

On the right side, the 7's cancel since 7/7 = 1.  Don't need a calculator for that.

anonymous · Answer

Ok. Then what ?

mertsj · Answer

Take the inverse cos of each side.

anonymous · Answer

Ok.... Doing what ?

mertsj · Answer

$$\frac{h}{7}=\cos (\frac{\pi}{3}t)$$

mertsj · Answer

That's what you have now, right?

anonymous · Answer

Right, So what next ? & what would my answer be.

mertsj · Answer

$$\cos^{-1}( \frac{h}{7})=\cos^{-1} (\cos (\frac{\pi}{3}t))$$

mertsj · Answer

Simplify the right side and then multiply both sides by 3/pi
