Question

Rewrite the expression as trigonmetric function of single angle measure.

tan 4 0 + tan 2 0 / 1- tan 4 0 2 0

A. tan 6 0
B. cot 6 0
C. tan 4 0
D. cot 4 0

Answer 1

look up tan(A+B) formula

Answer 2

\( \ tan(A+B) = \frac{\tan A + \tan B}{1 - \tan A \tan B}\)

Answer 3

doesnt the given expression looks like the right hand side of the formula ?

Answer 4

yea?

Answer 5

A = 40
B = 20

Answer 6

so it simplifies to left hand side \(\tan(A+B)\)

Answer 7

which is : \(\tan(40+20)\)

Answer 8

il leave the rest for u to complete (:
