Write the equation of the sine function with amplitude of 7, period of  2π , phase shift of 90°, and a vertical shift of 15.

What does all that mean?
For the general formula for sine
$$asin(bx-c) + d$$
amplitude = |a|
Period = 2pi/b
Phase Shift = c/b
Vertical shift = d
so where do we go from there?

Okay, so if you an amplitude of 7, that's more or less considered "a". 

asin(bx - c) + h

plainntall · Answer

1. Remember or Lookup the general form of a sine function
2. Substitute the numbers for the letters.

If Amplitude is a and it is equal to 7 then asin(bx-c) + d is
7sinx(bx-c) + d
continue substituting the numbers for the letters
