The hypotenuse (H) is the longest side of the triangle opposite to the 90 degree angle. The other two sides are known as the base (B) and perpendicular (P) side. The formula to find the hypotenuse is the square of the hypotenuse equals the sum of the squares of the base and the ...
For example, if you have an angle A = 40°, you can find sin A≈ 0.64. But you have to go the other direction when you’re solving a triangle. For instance, you might get sin B = 0.82 and have to find the angle B. You’re not asking what’s the sine of some angle, but ...
The Pythagorean Theorem can be used to find a side length when two sides of a right triangle are known. Sine, cosine, and tangent can be used to solve for missing sides if at least one side and one acute angle in a right triangle are known. The function used is determined by the ...

A normalized vector is any vector with the length 1. To find the normal vector of any given vector, divide both components of the vector by the vector's length. Multiplication. Multiplying a vector by a scalar factor will increase the magnitude of the vector. An easy way to d...
Calculate the sine value for one angle by dividing opposite side by adjacent side. Step 4 Find the quotient of sin(a)/A, and set it equal to x/B, where x is sin(b). Multiply both sides of the equation by B tosolve for x. ...
Students will need to have transferred the .tns file to their handheld prior to the start of the activity. They will move the triangle of the unit circle to find the angle measures listed in the table on the student worksheet. Students will record the values and then answer questions about...
For example, to find the derivative of sine, we need: and we let dx go to zero. This is tricky to work on directly, but using the sin(a+b) formula we have As dx goes to zero, cos(dx)=1 (zero angle is full width), so we have: And as dx goes to zero, sin(dx...
Find the exact values of the six trigonometric functions of the angle 495 degrees. Find the values of the trig functions of t from the given information. csc t = 5, cos t < 0 What is the exact value of the trigonometric function at the given real number: tan(5pi/4) What is the ...
What if I'm not allowed to draw pictures to find the angle values? If your instructor doesn't want you drawing pictures to help you remember the trigonometric values, then... don't let your instructorknowthat you're drawing the pictures. Use scratch paper that you don't hand in, or ...
