Trigonometry 10th

Assuming no transformation, what function is this

• y=sin x

• y=cos x

• y=tan x

• Neither

sin x or cos x?

• y=sin x

• y=cos x

• neither

A transformed sine function has amplitude of 4, and takes 5 units to complete a cycle. It also has a vertical translation of 2 units down and a horizontal translation of 3 units to the right. Write the equation of this sine function.

Which parent function is shown?

• $y=\tan x$

• $y=\sin x$

• $y=\csc x$

• $y=\sec x$
