C! Like terms refer to the variables that are the same, rather than the coefficients (the numbers).

Verify the identity: <br> (1-sinx)/cosx = cosx/(1+sinx)

Lisa [10]

For the answer to the question above,
<span>Let's work with the left-hand side
We're going to times cosx/1-sinx by 1+sinx/1+sinx, you can do this because 1+sinx/1+sinx is equal to 1, so you aren't really changing anything.

After you've times the top and bottom by 1+sinx, you get:

cosx(1+sinx) / (1-sinx)(1+sinx)

The denominator is a difference of squares, so you get 1-sin^2 x

what you have now is

cosx(1+sinx) / 1-sin^2x

You know that 1-sin^2x is equal to cos^2x

so know you have

cosx(1+sinx) / cos^2x

get rid of the cosx on top by simplifying and the cos^2x so that you're left with

(1+sinx) / cos x

Therefore cosx / 1- sinx = 1 + sinx / cos x</span>

Please help me with the problem

mixas84 [53]

Let's see what we're working on here

$\frac{1}{2} - 2(m) =?$
? = 0
$Simplify this →$ $\frac{1}{2}$

$\frac{1}2y} - 2(m) = ?$

$\frac{2(m)(2)}{2}$

$\frac{1 - 4(m)}{2} = ?$

$\frac{1 - 4(m)}{2} = 2$

$-4(m) + 1 = 0$
Subtract ( - )the number 1 from each of your sides on this part

4(m) = 1
Multiply( ×) the number -1 to your sides for this part of the equation

Therefore, the value of m is $\frac{1}{4}$
$m = \frac{1}{4}$
