Trigonometry
For the following trigonometric expression, evaluate and give the answer as an exact value in radians.
sin- 1(- (√2)/2)
cot- 1(- 1)
Without using a calculator, determine the exact value of the expression:
sin⁻¹ (-1/2)
Determine the exact value of the given inverse trigonometric function without using a calculator.
y=cos−1(−12)y=\(\cos\)^{-1}\(\left\)(-\(\frac\)12\(\right\))
y=sin−15y=\(\sin\)^{-1}\(\sqrt\)5
y=csc−1(−233)y=\(\csc\)^{-1}\(\left\)(-\(\frac{2\sqrt3}{3}\]\right\))
Find the value of the given inverse trigonometric function using a calculator. Write your answer in radians.
y=tan−1(1.5679827)y=\(\tan\)^{-1}(1.5679827)
