Find the distance between the points : `(cos theta, sin theta), (sin theta, cos theta)`

Evaluate the following: |costheta, -sin theta],[sin theta, cos theta]|

Prove the orthogonal matrices of order two are of the form [(cos theta,-sin theta),(sin theta,cos theta)] or [(cos theta,sin theta),(sin theta,-cos theta)]

If the coordinates of a variable point be (cos theta + sin theta, sin theta - cos theta) , where theta is the parameter, then the locus of P is

sin^(3)theta + sin theta - sin theta cos^(2)theta =

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

if theta is a parameter then x=a ( sin theta + cos theta), y=b( sin theta - cos theta ) respresents

Solve sqrt(3) cos theta-3 sin theta =4 sin 2 theta cos 3 theta .

(1+sin 2theta+cos 2theta)/(1+sin2 theta-cos 2 theta) =

Find the value of (1+cos theta+sin theta)/(1-cos theta +sin theta)

Find the A.M. between: ( cos theta + sin theta )^(2) and ( cos theta - sin theta)^(2)
