Evaluate:
`|[sectheta,tantheta],[tantheta,sectheta]|`

tantheta-tantheta/2=sectheta/2

Evaluate : |A| = [[sectheta , tantheta ],[tantheta ,sectheta]]

(tantheta-sectheta)^2

The inverse of the matrix [[sectheta, tantheta], [tantheta, sectheta]] is

Simplify tan theta [(sectheta,tantheta),(tantheta,-sectheta)]+sectheta[(-tantheta,-sectheta),(-sectheta,tantheta)]

If A=[[sectheta, tantheta], [tantheta, sectheta]] , then

If sectheta+tantheta=p , then sectheta=?

If A=[[sectheta, tantheta, 0], [tantheta, sectheta, 0], [0, 0, 1]] , then A^(-1)=

If sectheta+tantheta=2 , then the value of sectheta is

tantheta+sectheta=sqrt(3)
