" Simplify "cos theta[[cos theta,sin theta],[-sin theta,cos theta]]+sin theta[[sin theta,-cos theta],[cos theta,sin theta]]

Simplify, costheta[[cos theta, sin theta],[-sin theta, cos theta]] + sin theta [[sin theta, -cos theta],[cos theta, sin theta]]

[[ Simplify :cos thetacos theta,sin theta-sin theta,cos theta]]+sin theta[[sin theta,-cos thetacos theta,sin theta]]

cos theta+sin theta=cos2 theta+sin2 theta

cos theta/(1+sin theta)=(1-sin theta)/cos theta

Evaluate |[cos theta, -sin theta], [sin theta, cos theta]|

(i) |(cos theta,-sin theta),(sin theta,cos theta)|

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 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 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))
