Question

* If cos square A= |- Cos to the power 4 a
then proof that,
cot to the power 4 a-cot square A=1
* Cos theta+ sin theta = √2 cos theta .then cos theta - sin theta =?​

Answer 1

Answer:

1+cos A

tan- A

27.

II

1 - cos A

80

(sec A - 1)

If cos e

4

3

, tan =

5

4

then find sine

Step-by-step explanation:

* If cos square A= |- Cos to the power 4 a

then proof that,

cot to the power 4 a-cot square A=1

* Cos theta+ sin theta = √2 cos theta .then cos theta - sin theta =?
