Question

Trigonometric Equation

tanA cosA + √(3) cosA = 0

Answer 1

\[
\tan(A) \cos(A) + \sqrt 3 \cos(A)=0\\

\cos(A) (\tan(A) ) + \sqrt 3 )=0
\]
Can you finish it now?

Answer 2

NOw you have two equations to solve
\[

\cos(A) =0 \\ \text { or }\\
\tan(A) + \sqrt 3 =0

\]

Answer 3

So
\[
A= \frac \pi 2 + k \, \pi\\
A= -\frac \pi 3 + k \,\pi
\]

Answer 4

please simplify.
i'm new to this lesson
i really dont get you

Answer 5

Do you know when cos(x)=0?

Answer 6

nope

Answer 7

Try to go back to your book and study the function cos and tan etc before.

Answer 8

i dont even know how to start solving this
