That would be called the solution
Answer:
Maybe its because you give useless answers to get points.
Idiot.
-5 Subtract 8 from -12 and divide -20 by 4 and get -5
is proved
<h3><u>
Solution:</u></h3>
Given that,
------- (1)
First we will simplify the LHS and then compare it with RHS
------ (2)

Substitute this in eqn (2)

On simplification we get,


Cancelling the common terms (sinx + cosx)

We know secant is inverse of cosine

Thus L.H.S = R.H.S
Hence proved
It would take 1 1/2 hour to walk three miles.
