**Math Trigonometry Using Sin Cos or Tan to Find an Angle**

The cosine (cos) of an acute angle in a right angled triangle is the ratio between the side adjacent to the angle and the hypotenuse of the triangle. Example 5 Use the cosine function to find the angle A giving your answer to the nearest degree .... 2/05/2008 · Please can someone help me on how to use it using a standard casio science calcualtor. I have forgotten how to use sin,cos and tan and sin cos and tan to the -1. For instance how would I work out, two sides of a triangle are 2.3 and 5.4 and one angle is 90. so I have to use cos, beacuse of soh,cah,toa. how would i do cos-1 (2.3/5.4

As suggested by Jonas: 1) Draw a right triangle and label one of the (non $90^\circ$) angles $\alpha$. 2) You know that the tangent of $\alpha$ is ${1\over2}$. how to use expressed breast milk This enables you to work out the angle if you have the sin, cos or tan of it. In other words: Sin (90) = 1. Sin −1 (1) = 90° Trigonometry and Calculators. Scientific calculators have sin, cos, and tan functions, as well as inverse functions. It’s worth taking a few minutes to work out how your calculator operates, as this could save you hours of messing about when you need it. Other

How to use sin, cos and tan continues….. with a video on finding the missing length in a right angle triangle. Watch the video and try the quick test.

- Using the arcsine (inverse sine) we can find the angle a using the equation The screen shot below shows how we used Excel to determine that the launch angle of the ramp is 14.04°. Note the use of the DEGREES( ) and RADIANS( ) function in the above example.
- The trigonometric function tangent, like the sine and the cosine, In math class, the tangent of an angle can be found using the ratio comparing the length of the side opposite the angle (o) to the length of the side adjacent to the angle (a). The formula for this ratio can be written: Tan Θ = o/a. where Θ is the size of the angle under consideration (45o in this example) In Excel
