Question

Sinusoidal means looking like a basic sine graph. By how many degrees do you have to shift sin x = y to the right to make it look like the graph of cos x = y? (Enter only the number of degrees.)

Answer 1

90

Answer 2

Select all the true statements about the graphs of these two functions.
•h(x) = sin (x + ð/4)
•h(x) = cos (x - ð/4)
Ans:The sine function is shifted to the left by ð/4, while the cosine function is shifted to the right by ð/4.

The graphs of these two functions coincide.

Answer 3

correct
