Question 866724
Verify the identitiy: csc x/ sin x - cot x/tan x = 1
{{{csc x/ sin x - cot x/tan x = 1}}}
start with left side:
{{{(1/sinx)/sin x-(cosx/sinx)/(sinx/cosx)}}}
{{{1/sin^2(x)-cos^2(x)/sin^2(x)}}}
{{{(1-cos^2(x))/sin^2(x)}}}
{{{(1-cos^2(x))/(1-cos^2(x))=1}}}
Verified: left side=right side
