Evaluate `|[ 2 cos theta , 2 sin theta],[sin theta, cos theta]|`

Find the value of |[cos theta,-sin theta],[sin theta,cos theta]|

If A=[cos2 theta sin2 theta-sin2 theta cos2 theta], find A^(2)

Evaluate: int cos2 theta ln((cos theta+sin theta)/(cos theta-sin theta))d theta

If cos2theta=0 , then |(0,costheta,sin theta),(cos theta, sin theta, 0),(sin theta, 0, cos theta)|^(2) is equal to…………

If f(theta)=|[cos^(2)theta,cos theta sin theta,-sin theta],[cos theta sin theta,sin^(2)theta,cos theta],[sin theta,-cos theta,0]| , then f((pi)/(12))

If f (theta) = [[cos^(2) theta , cos theta sin theta,-sin theta],[cos theta sin theta , sin^(2) theta , cos theta ],[sin theta ,-cos theta , 0]] "then " f (pi/7) is

If A=[[cos2 theta,sin2 theta],[-sin2 theta,cos2 theta]] then find A^2

If A=[[cos 2 theta, sin 2 theta],[-sin2theta, cos2theta]] , find A^2

The value of (cos^6 theta+sin^6 theta+ 3sin^2 theta cos^2 theta)/(cosec theta sec theta(sin theta+cos theta-1)(sin theta+cos theta+1)) is : (cos^6 theta+sin^6 theta+ 3sin^2 theta cos^2 theta)/(cosec theta sec theta(sin theta+cos theta-1)(sin theta+cos theta+1)) का मान ज्ञात कीजिए?
