Use the fundamental identities to simplify the expression si

Use the fundamental identities to simplify the expression. sin theta/tan theta a. cot theta b. cot theta c. sec theta d. cos theta d. csc theta Use the trigonometric substitution to rewrite the algebraic expression as a trigonometric function of theta. where 0

Solution

Solution:

23.

sin / tan = sin /( sin/cos)

=> sin / tan = cos

24.

Here;

srqt(x^2 - 16)

=> srqt(4²sec² - 16)

=> srqt{16(sec² - 1}

=> srqt(16tan²)

=> 4tan
