Look at the picture below. What is tan(A – B)? Thanks!

1 answer:

3 0

Step-by-step explanation:

the mistake was made when the value of cos 3 pi over 2 was calculated.

tan(A-B)= ?since tan=sin/cos

sin(A-B) = sinAcosB-cosAsinB

cos(A-B) cosAcosB+sinAsinB

divide by cos on the RHS

tan(A-B)= tanA-tanB

1+tanAtanB

Answer: $\bold{(C)\ \dfrac{3 - x}{x(x-1)}}$

Step-by-step explanation:

$\dfrac{2}{x^2-x}-\dfrac{1}{x}$

$=\dfrac{2}{x(x-1)}+\dfrac{-1}{x}$

$=\dfrac{2}{x(x-1)}+\dfrac{-1}{x}\bigg(\dfrac{x-1}{x-1}\bigg)$

$=\dfrac{2}{x(x-1)}+\dfrac{-x+1}{x(x-1)}$

$=\dfrac{2-x+1}{x(x-1)}$

$=\dfrac{3-x}{x(x-1)}$
