Geometry8.4 Relations between Sin θ, Cos θ and Tan θ

 The ratios sin θ, cos θ and tan θ of an angle are very closely related. If one of them is known, the other two can be easily determined. Example: If sin θ = 3/5, find tan θ, θ is acute. cos θ = 4/5 tan θ = sin θ/ cos θ = 3/4 Directions: Answer the following questions. Also write at least ten examples of your own.
