the figure shows an angle θ in standard position with its terminal side intersecting the unit circle. evaluate the six circular function values of θ. sin θ = - 3/5 (simplify your answer, including any radicals. use integers or fractions for any numbers in the expression.) cos θ = (simplify your answer, including any radicals. use integers or fractions for any numbers in the expression.)
Answer
Explanation:
Step1: Recall circular - function definitions
For a point ((x,y)) on the unit - circle and an angle (\theta) in standard position whose terminal side intersects the unit - circle at ((x,y)), (\sin\theta=y), (\cos\theta = x), (\tan\theta=\frac{y}{x}(x\neq0)), (\csc\theta=\frac{1}{y}(y\neq0)), (\sec\theta=\frac{1}{x}(x\neq0)), (\cot\theta=\frac{x}{y}(y\neq0)).
Step2: Identify (x) and (y) values
The point on the unit - circle is ((x,y)=\left(-\frac{4}{5},-\frac{3}{5}\right)).
Step3: Calculate (\cos\theta)
Since (\cos\theta=x), then (\cos\theta =-\frac{4}{5}).
Step4: Calculate (\tan\theta)
(\tan\theta=\frac{y}{x}=\frac{-\frac{3}{5}}{-\frac{4}{5}}=\frac{3}{4}).
Step5: Calculate (\csc\theta)
(\csc\theta=\frac{1}{y}=\frac{1}{-\frac{3}{5}}=-\frac{5}{3}).
Step6: Calculate (\sec\theta)
(\sec\theta=\frac{1}{x}=\frac{1}{-\frac{4}{5}}=-\frac{5}{4}).
Step7: Calculate (\cot\theta)
(\cot\theta=\frac{x}{y}=\frac{-\frac{4}{5}}{-\frac{3}{5}}=\frac{4}{3}).
Answer:
(\cos\theta =-\frac{4}{5}), (\tan\theta=\frac{3}{4}), (\csc\theta =-\frac{5}{3}), (\sec\theta =-\frac{5}{4}), (\cot\theta=\frac{4}{3})
