Question

1+ cos A = (cosec A+ cot A)?
1-cos A​

Answer 1

Step-by-step explanation:

(1+cosA)

L. H. S. =------------------

(1-cosA)

(1+cosA)(1+cosA)

=--------------------------------

(1-cosA) (1+cosA)

(1+cosA)^2

=----------------------

(1)^2-(cosA) ^2

(1+cosA)^2

=--------------------

1-cos^2A

(1+cosA)^2

=----------------------

sin^2A

= (1+cosA/sinA)^2

=(1/sinA+cosA/sinA)^2

=(cosecA+cotA)^2
