Answer 2

Answer:

Hi your answer is as follows

Step-by-step explanation:

cosec = 1/sin

sec = 1/cos

tan = sin/cos

cot = cos/sin

substituting the values in the equation we get,

$(\frac{1}{sin} -sin)(\frac{1}{cos} -cos)(\frac{sin}{cos} +\frac{cos}{sin} )$

finding LCM we get,

$(\frac{1-sin^{2} }{sin} )(\frac{1-cos^{2} }{cos} )(\frac{sin^{2}+cos^{2} }{sin*cos} )$

we know that ,

$sin^{2} +cos^{2} =1\\sin^{2} =1-cos^{2} \\cos^{2} =1-sin^{2}$

on substituting the values above in the equation we get,

$(\frac{cos^{2} }{sin} )(\frac{sin^2}{cos} )(\frac{1}{sin*cos} )$

on multiplying the three values we get,

$\frac{cos^2*sin^2*1}{sin^2cos^2}$

as we can cancel them out we remain with 1

Hence proved,
