Question

2cosA + SinA = 2. find cotA
​

Answer 1

Answer:

cosecA=2 or sinA=21

∴A=30∘

∴cosA=23

Now,

cotA+1+cosAsinA

=cot30∘+1+cos30∘sin30∘

=3+1+2321

=3+2+312−32−3

=3+4−32−3

Answer 2

Answer:

cosecA=2 or sinA=21

∴A=30∘

∴cosA=23

Now,

cotA+1+cosAsinA

=cot30∘+1+cos30∘sin30∘

=3+1+2321

=3+2+312−32−3

=3+4−32−3.
