Intro to Inverse Functions

Which function deals with opposite over hypotenuse? Remember: SOH CAH TOA

• Sine

• Cosine

• Tangent

How would you solve 

• Take the square root of each side

• Divide each side by 2

How would you "undo" a square root?

• Square the number

• Divide the number 

• Multiply the number

To find a missing angle using SOH CAH TOA, you have to take the OPPOSITE of a function (sine, cosine, or tangent)?

• True

• False

What do you get when you type in the inverse sine of 6/18?
