Question

s

Answer 1

They are asking you to leave the left hand side alone; and manipulate the right-hand side until it is exactly like the left.

Answer 2

How would you do that since there is tan on the other side?

Answer 3

There is what they call trig identities; you substitute.

Answer 4

those?

Answer 5

Those are the only ones we use and I don't understand how to use them to do these.

Answer 6

That's a start, eg, from the chart there is a 1 + (tan^2) x = (sec^2) x. You can start my manipulating part of it into 1 + (tan^2)

Answer 7

One minute. I'm trying possibilities.

Answer 8

It is real hairy. Re-read make sure you didn't make a mistake in writing down the problem.

Answer 9

I just looked at it, it's correct.

Answer 10

The left-hand side is multiplied, not added?

Answer 11

I think it is all one thing on the left. I don't think the x means multiply. That's how it's written.

Answer 12

ok I got this but I don't know what to do after

\[cotx(1+2\tan^2x)^2=cotx+2\tan^3x\]

Answer 13

It should be \[1+ \tan ^{2}x\]

Answer 14

Is the squared on the outside still right?

Answer 15

yes

Answer 16

Is it finished after that? I don't see anything else to do for it.

Answer 17

Each side should be identical. I was working at it but I'm stumped.

Answer 18

Are any of the other ones easier?

Answer 19

These are torturous, what level, what course?

Answer 20

Pre-calc honors. Online..

Answer 21

Sorry, you'll find nothing this difficult in calculus.
