Question

proove that (1+cot^a) sin^a=1​

Answer 1

Answer:

hope it helps

Step-by-step explanation:

= (1+cot^2 ) sin^2 A

$= > (1 + \frac{cos ^{2} \: a}{sin {}^{2} \: a} \: )sin {}^{2} \: a$

Taking LCM,

$= > ( \frac{sin {}^{2} \: a \: + cos {}^{2} \: a}{sin {}^{2} } ) \: sin {}^{2} \: a$

$= > sin \: {}^{2} \: a \: + cos {}^{2} \: a$

$= > 1$

Hence proved...
