Ex 22 16 Find the values of sin-1sin2π3 Let y sin-1 sin 2𝜋3 sin y sin 2𝜋3 sin y sin 120 But range of principal value of sin-1 is π2 π2 ie.
Sin 2pi 3. -90 90 Hence y 120 not possible Now sin y sin 120 sin y sin 180 60 sin y sin 60 sin y sin 60 𝜋180 sin y sin 𝜋3 Hence y 𝜋3 Which is in. Evaluate sin-2pi3 Move the negative in front of the fraction. Find the Exact Value sin2pi3 Apply the reference angle by finding the angle with equivalent trig values in the first quadrant.
The exact value of is. Idk how to work it out I know you have to use sinab sin a cos b cos a sin b but I cant get it to work out. Apply the reference angle by finding the angle with equivalent trig values in the first quadrant.
Make the expression negative because sine is negative in the third quadrant. Compute answers using Wolframs breakthrough technology knowledgebase relied on by millions of students professionals.
