Simplify the following term
`(1+sintheta)(1+costheta)`

(1+costheta)/(sintheta)=?

Prove the following Identities (1+sin theta-costheta)/(1+ sintheta+costheta)= tan(theta/2)

Evaluate : ( 1 + sintheta + costheta )^2 =

If 0^(@)lethetale90^(@) , then solve the following equations : (i) (costheta)/(1-sintheta)+(costheta)/(1+sintheta)=4 (ii) (cos^(2)theta-3costheta+2)/(sin^(2)theta)=1 (iii) (costheta)/("cosec"theta+1)+(costheta)/("cosec"theta-1)=2

Simplify costheta[costhetasinthetasinthetacostheta]+sintheta[sintheta-costhetacosthetasintheta]

If sintheta=(7)/(25) ,then find the value of sqrt((-1costheta)/(1+costheta)) .

Choose the correct answer from the following : The value of |{:(-costheta,sintheta),(-sintheta,-costheta):}| is:

Choose one of the following options which is equal to: (1+costheta)/(sintheta)

Simplify : 1/( Costheta Sintheta ) + ( Costheta Sintheta )/( CosthetaSintheta )

If cot theta= (7)/(8) then the value of ((1+ sintheta)(1-sintheta))/((1+costheta)(1-costheta)) = …………….
