Convert the following angles to Radians. Provide Exact Answers

Convert the following angles to Degrees. Round to the nearest degree.

Question 3: Finding the Arc Length

Question 6: Solve the Equation

What is a Radian? Much like a degree, a Radian is a measurement of an angle. The radian measure of an angle,ϴ, is defined as the length, a, of the arc that “subtends” the angle divided by the radius of the arc,r

Radian Relationship to Degrees

Word Problems

Trig Ratios

Finding Trig Ratios

Solving Trig Equations

Graphing Trig Functions We sketched the graphs of all 6 trig functions We found the characteristics of each of these trig functions: -Max/Min -Amplitude -Period -Intercepts -Asymptotes

Transformations of Sinusoidal Functions

Applications of Sinusoidal Functions We applied sine and cosine functions to real life scenarios where we: Sketched the function Found the characteristics of the function Found the equation of the function that would model the scenario Solved for specific values of the function
