**Trig Equations**

An SQA N5 Maths exam question on Trig Equations is shown below:

Solve the equation 11cosx° – 2 = 3 for 0 ≤ x ≤ 360°

Source: N5 Maths, 2014, P2, Q12

Solving equations such as *sin x° = 1, sin x° = – 1* and *cos x° = 0* can be achieved just be reading the solutions from the trig graphs. For example, in the graph of* y = sin x°* below, it can be seen that if we draw a horizontal line from 1 on the y-axis then it will meet the sin wave at 90°. Therefore the solution to* sin x° = 1* is *x = 90°.*

Solving Trig Equations such as *sin x° = 0.5* is more complicated**. **

In the graph of* y = sin x°* above, it can be seen that a horizontal line from 0.5 on the y-axis then it will meet the sin wave at two places.

A calculator is required for the first solution:

x = inverse sin (0.5) = 30°

The correct use of the CAST Diagram is required to find the second solution:

x = 180° – 30° = 150°
