5.5: Finding Angles

Find the inverses for the functions below 𝑦=2𝑥 𝑦= 𝑥 𝑦= 𝑥 3 𝑦=𝑠𝑖𝑛𝑥

The three inverse trig functions are known as arc functions. The inverse of sine is arcsine Cosine and Tangent have inverses of arccos and arctan, respectively These can also be denoted as 𝑆𝑖𝑛 −1 and so on.

Evaluate the following arcsin(1) arctan(4) arccos(2) arcsin(sin(x))

Solve the equation 𝑠𝑖𝑛𝑥= 3 2

Evaluate the following: tan(𝑎𝑟𝑐𝑡𝑎𝑛 6 11 )

Evaluate the following: cos(𝑎𝑟𝑐𝑠𝑖𝑛 2 3 )

If D is the midpoint of BC, and BC=14, find x and the length of both hypotenuses

5.6: The Law of Sines

What are the requirements for solving any of these trig. problems?

The law of Sines relates the sides of ALL triangles It states that the ratio of any side with the sine of the opposite angle is the same. Or…
