Question

prove that-
√1-cosA/1+cosA + √ 1+cosA/1-cosA= 2 cosecA​

Answer 1

Answer:

2 cosec a

Step-by-step explanation:

$(\sqrt{1-cos a} *\sqrt{1-cos a} +\sqrt{1+cos a} * \sqrt{1+cos a} )/\sqrt{1-cos a} *\sqrt{1+cos a} \\(1+cos a + 1-cos a)/1^{2} - cos a^{2} \\2/sin a^{2} (1-cos a^{2}=sin a^{2}) \\ 2 cosec a$

Answer 2
