Question

Solve the equation exactly on 0 lessgreater than t less greater than 2phi

Answer 1

Step 1: Problem

sint = -1

Step 2: Concept and method

`\begin{gathered} \sin \text{ t = -1} \\ \text{Next find the inverse of sin} \\ t\text{ = }\sin ^(-1)(-1) \\ t\text{ = -90} \end{gathered}`

Step 3: Final answer

`\text{Therefore, the value of t in the interval 0}\leq\text{ t }\leq\text{ 2}\pi\text{ = 0 }\leq\text{ t }\leq\text{ 360}`

t = 270
