Question

1. Use a calculator to find all solutions in the interval (0, 2π). Round the answers to two decimal places. (Enter your answers as a comma-separated list. If there is no solution, enter NO SOLUTION.)
sin x cos x = 0.027

2. Use a calculator to find all solutions in the interval (0, 2π). Round the answers to two decimal places. (Enter your answers as a comma-separated list. If there is no solution, enter NO SOLUTION.)
cot x = −2.83

Answer 1

Stuck!

Answer 2

sin x cos x = 0.027
note: this is very very similar to sin 2x = 2 sin x cos x

cot x=-2.83
note: \(cot x = \frac{1}{tan x}\)

Answer 3

Yeah I get that part, but I get stuck right after...

Answer 4

ah the calculator part?
sin 2x = 0.027
\(2x= sin^{-1} 0.027\)
just press the \(sin^{-1}\) button
