Question

pls it's urgent I have exam tomorrow..........pls help me​

Answer 1

Answer:

Correct Answer is [2 ] 1+p/1-p

Step-by-step explanation:

cos(A) = (q - 1)/(q p +1) and sin(A) = (p + 1) /( q p +1 ) and

A = arctan( ( p +1) /(q -1) )

The standard triangle construction then gives

sin(A) = (p+1) / SS and cos(A) = (q - 1)/SS where SS = sqrt( (p+1)^2 +(q-1)^2)

It is easy to show that q = (1 + cos(A) )/(sin( A))

From there make the substitutions for sin(A) and cos(A)
