Question

prove that [cosec (90-theta) -sin(90-theta) ] [(cosec -sin theta) (tan -cot theta) ] =1​

Answer 1

Answer:

prove that [cosec (90-theta) -sin(90-theta) ] [(cosec -sin theta) (tan -cot theta) ] =1

if cot ^2 (sec-1 ) 1+ cos) = k cos find kin a triangle ABC right angled at B if baseline is a b equal to 12 and 20 equal to 5 then determine cos cIf A B C are interior

angles

of ABC then cos c/2 is equal

To

Step-by-step explanation:

1+cos A

tan- A

27.

II

1 - cos A

80

(sec A - 1)prove that [cosec (90-theta) -sin(90-theta) ] [(cosec -sin theta) (tan -cot theta) ] =1* 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 =?
