Prove that csc x - cot x is the same as (sin x)/(1 + cos x)

Lera25 [3.4K]

$\csc x-\cot x=\dfrac{\sin x}{1+\cos x}\\\\L_s=\dfrac{1}{\sin x}-\dfrac{\cos x}{\sin x}=\dfrac{1-\cos x}{\sin x}\\\\R_s=\dfrac{\sin x}{1+\cos x}\cdot\dfrac{1-\cos x}{1-\cos x}=\dfrac{\sin x(1-\cos x)}{1^2-\cos^2x} =\dfrac{\sin x(1-\cos x)}{1-\cos^2x}\\\\=\dfrac{\sin x(1-\cos x)}{\sin^2x}=\dfrac{1-\cos x}{\sin x}\\\\L_s=R_s$

$\text{Used:}\\\\\csc x=\dfrac{1}{\sin x}\\\\\cot x=\dfrac{\cos x}{\sin x}\\\\a^2-b^2=(a-b)(a+b)\\\\\sin^2x+\cos^2x=1\to\sin^2x=1-\cos^2x$

Q4H: The question is in the picture below (please show work) :

Ipatiy [6.2K]

-3x-5=16
-3x-5(+5)=16+5
-3x=21
-3x/-3=21/-3
x=-7

-4(y-2)=12
-4y+8=12
-4y=4
y=-1

8.88=4.44(x-7)
8.88=4.44x-31.08
39.96=4.44x
9=x

5(y+2/5)=-13
5y+2=-13
5y=-15
y=-3
