Question

if tanA =p/q find the value of cosA+sinA/cosA-sinA
​

Answer 1

Answer:

Step-by-step explanation:

tanA=p/q

=>P/B=p/q

H=√P²+B²

=√p²+q²

=>sinA=P/H=p/√p²+q²

=>cosA=B/H=q/√p²+q²

(cosA+sinA) /(cosA - sinA)

=(q/√p²+q²+p/√p²+q²) /(q/√p²+q²-p/√p²+q²)

=(q+p/√p²+q²) /(q-p/√p²+q²)

=q+p/q-p
