Sin2 theta + Cos2 theta =1
1 - sin2 Thera = Cos2 theta
1- cos2 theta = sin2 theta
1+ tan2 theta = Sec2 theta
Sec2 theta - tan2 thetaqq = 1
Sec2 theta - 1 = tan2 theta
1+ cot2 theta = cosec2 theta
Cosec2 theta - cot2 theta = 1
Cosec2 theta - 1 = cot2 theta
Sun (90-theta) = cos theta
Cos (90- theta) = sin theta
Tan (90- theta) = cot theta
Cot (90-theta) = tan theta
Sec (90 - theta) cosec theta
Cosec (90 - theta) = sec theta
Sin theta / cos theta = tan theta
Cos theta / sin theta = cot theta

Plzz here is a doubt why we use 90° as theta
@Ananyajain-sg8wb
@Ananyajain-sg8wb Жыл бұрын
Becoz the value sin 90 is 1 and if we will add sin1 + sin2 + sin3 so this should be equal to 3 As it is mentioned in the question
