is proved
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
Answer:
12
Step-by-step explanation:
Alright so we are asked to find the intersection of y=(x-8)^2 and y=36.
So plug second equation into first giving: 36=(x-8)^2.
36=(x-8)^2
Take square root of both sides:
Add 8 on both sides:
x=8+6=14 or x=8-6=2
So we have the two intersections (14,36) and (2,36).
We are asked to compute this length.
The distance formula is:
.
I could have just found the distance from 14 and 2 because the y-coordinates were the same. Oh well. 14-2=12.
