MYP Extended Mathematics 7 Trigonometric Functions and Rules Questionbank

Which of the following functions represents the graph of $y = \sin x$ after it has been translated 5 units up and then stretched vertically by a factor of 2?

An object's vertical position is modeled by the function

where $t$ is time in seconds. If the object is at its midline (principal axis) and moving upward at $t = 1$, find the smallest non-negative value for the phase shift $C$.

The side lengths $b$ and $c$ must be larger than $a$ for the cosine rule to work.

The value calculated for $\cos A$ was less than $-1$, and these side lengths cannot form a triangle.

The angle $A$ is exactly $180^{\circ}$ and the calculator cannot process it.

The calculator was in Radian mode instead of Degree mode.

$h = b \sin A$ and $h = b \sin C$

$h = c \sin A$ and $h = a \sin C$

$h = a \sin A$ and $h = c \sin C$

$h = c \cos A$ and $h = a \cos C$
