Question

Trigonometric equations

2sin(theta) + 3 = 4

Answer 1

`\qquad\qquad\huge\underline{{\sf Answer}}♨`

Let's solve for x ~

`\qquad \sf  \dashrightarrow \:2 \sin(x) + 3 = 4`

`\qquad \sf  \dashrightarrow \:2 \sin(x) = 4 - 3`

`\qquad \sf  \dashrightarrow \:2 \sin(x) = 1`

`\qquad \sf  \dashrightarrow \:\sin(x) = (1)/(2)`

`\qquad \sf  \dashrightarrow \:x = 30 \degree \: \: or \: \: (\pi)/(6) \: rad`
