Question

2. sin A. COSA. tanA + COSA. sinA. cotA​

Answer 1

Step-by-step explanation:

The value of (sinA+cosA)(tanA+cotA) is

=(sinA+cosA)(cosAsinA+sinAcosA)

=(sinA+cosA)(cosAsinAsin2A+cos2A)

=cosAsinAsinA+cosA

=cosAsinAsinA+cosAsinAcosA

=cosA1+sinA1

=secA+cosecA

Answer 2

Step-by-step explanation:

substitue tan and cot in terms of sin and cos

then

sin^2+cos^2=1
