Question

Simplify the following question

Answer 1

− 2sin(b) / cos(2b)

​

Explanation:

DIFFERENTIATE W.R.T. B is a different method entirely

We simply add together the numerators and set with 2cos

then keep this number and add to sinb and square it.

then repeat initial 2 + cosb ^2 but instead of multiplying its add.

Then set the whole division to -sin (2b) squared then +1

− 2cos(b)(3(sin(b))^2+(cos(b))^2) / −(sin(2b)) ^2 +1
