Find all solutions
The image contains handwritten equations and solutions that appear to be from a mathematics exercise focusing on trigonometric identities and equations. 

---

Equation 21: 

The problem is:

\[ 4\sin\theta - 1 = 2\sin\theta \]

To solve for \(\sin\theta\):

\[ \sin\theta = \frac{2\sin\theta + 1}{4} \]

---

Next to the equations for Exercise 21, there are unrelated mathematical solutions without clear instructions:

\[ \frac{2\pi}{3} + 2\pi n \]

\[ \frac{\pi}{3} + \pi n \]

Equation 29:

Given:

\[ \tan 3x = \]

Solutions are partially visible:

\[ 3x = \frac{\pi}{6} \]

These sections are part of solving trigonometric equations to find the angles that satisfy the equation, given \(\theta\) or \(x\) in trigonometric functions. The letters \(n\) typically denote any integer, suggesting multiple solutions based on periodic properties of trigonometric functions.

Expert Solution
Step 1

Given:

4 sin(θ)-1=2 sin(θ) sin(θ)=2 sin(θ)+14

We have,

sin(θ)=2 sin(θ)+14............(1)

Substitute sin(θ)=u in (1) we get,

u=2 u+14Multiply by 4 both sides,4u=2u+1Subtract 2u both sides,2u=1Divide by 2 both sides,  u=12
