How to Use Cosine to Solve a Word Problem? Example: A ramp is pulled out of the back of truck. There is a 38 degrees angle between the ramp and the pavement.If the distance from the end of the ramp to to the back of the truck is 10 feet. how to support a rainbow child 22/12/2018 · To remember the trigonometric table, use the acronym "SOHCAHTOA," which stands for "Sine opposite hypotenuse, cosine adjacent hypotenuse, tangent opposite adjacent. For example, if you wanted to calculate the sine of an angle or triangle, you'd know that sine is "sine opposite hypotenuse" based on "SOHCAHTOA." Therefore, you would just divide the opposite side of the …

- We can obtain the sine and cosine ratios from the right angle triangle. In a right angle triangle we have to find the sine ration using the opposite side and hypotenuse. Likewise we have to obtain the cosine rations using the adjacent side and hypotenuse of the right angle triangle.
- They are all ratios of different sides of triangles. Have you learned "SOH-CAH-TOA"? Sine is the ratio of the opposite side over the hypotenuse, cosine is the ratio of the adjacent side over the hypotenuse, and tangent is the ratio of the opposite side over the adjacent side.
