To find the volume of a prism, doesn't apply to all, but for a rectangle, to Base*Height*Length. Or you just need to find out the base and multiply by height. That's volume

For area, just do the length*width or depending on the shape, see how many other shapes are in there. Like how two right triangles= square, find the area of a square and/2.

Match each trigonometric function with its Unit Circle definition. Note that Angle A is correctly oriented for the Unit Circle d

PtichkaEL [24]

The first diagram below shows a circle with a radius of 1 (unit circle). The circle is drawn on a Cartesian graph with (0,0) as the center of the circle.

From the second diagram, we can determine the value of sin(Θ) = y
and cos(Θ) = x

We can further deduce that
tan(Θ) = $\frac{y}{x}$
sec(Θ) = $\frac{1}{cos(Θ)}$ = $\frac{1}{x}$
cosec(Θ) = $\frac{1}{sin(Θ)}$ = $\frac{1}{y}$
cot(Θ) = $\frac{cos(Θ)}{sin(Θ)}$ = $\frac{x}{y}$
