Cot x/ tan x × sec²x = cosec x how? prove it
We have;
#(cosx/sinx)/(sinx/cosx) xx 1/cos^2x = 1/sinx#
#cos^2x/sin^2x xx 1/cos^2x = 1/sinx#
#1/sin^2x = 1/sinx#
This is clearly FALSE so the identity cannot be proved. We can confirm graphically.
Since the two curves don't lie directly on each other, the given expression is an equation not an identity.
Hopefully this helps!

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
