In this video, you will learn how to find the measure of an acute angle in a right triangle using the inverse sine function. The video explains the ratios of side lengths for the trigonometric functions and introduces the concept of...

We need to know the initial velocity of a projectile leaving the Nerd-A-Pult. That means we need the initial speed and the initial angle. This video shows exactly how I measured both.

A 5.3 g dart is moving vertically at 16.5 m/s just before it collides with and sticks to a 33.9 cm long, thin piece of cardboard. If the dart hits the 71.8 g piece of cardboard 28.7 cm from its fixed end, to what maximum angle does the...

This video explains how to use inverse trigonometric functions to find angle measures in right triangles. It covers the definitions and properties of inverse trig functions and demonstrates their application through example problems.

In this video, the teacher explains how to find the angle of elevation or depression in a right triangle. Using the concepts of inverse trigonometric functions and the side lengths of the triangle, the teacher demonstrates how to set up...

👉 Learn how to evaluate inverse trigonometric functions. The inverse trigonometric functions are used to obtain theta, the angle which yielded the trigonometric function value. It is usually helpful to use the calculator to calculate the...

Now that we have dropped the ball into the bucket, we can determine the final velocity of the ball right before it strikes the bucket. Don't forget that velocity is a vector and has both magnitude and direction. Yep, component vector...

Understand the forces acting on an object on an incline by analyzing the forces on a “floating block”.

Mr.p throws a ball toward a bucket that is 581 cm away from him horizontally. He throws the ball at an initial angle of 55° above the horizontal and the ball is 34 cm short of the bucket. If mr.p throws the ball with the same initial...
