Question

how to solve for feda when cos(theta)=-0.19?

Answer 1

I'm sorry that wasn't for you.

Answer 2

I have so many tabs open, I got mixed up.

Answer 3

And I was just joking around with my freinds.

Answer 4

ok,np

Answer 5

theta = anticos (-0.19)

Answer 6

feda = anticos (-0.19)

Answer 7

\[\theta=\cos ^{-1}(-0.19)\] like this, and you were actually right the first time, its theda

Answer 8

I did this but in the back of the book it says the answers are both 1.76 and 4.90 and i dont know how to get it

Answer 9

The original question was...solve each equation for \[0 \le \theta <2\pi\] Give solutions to the nearest hundredth of a radian

Answer 10

use a calculator
set it to radians
