### To solve the expression sin 2pi 3 we can convert first 2pi 3 into degrees.

**What is sin2pi 3**. Evaluate sin 2pi 3 move the negative in front of the fraction. Add full rotations of until the angle is between and. The antiderivative of the sine is equal to cos x.

The consequence for the curve representative of the sine function is that it admits the origin of the reference point as point of symmetry. Find the exact value sin 2pi 3 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.

Using special triangle 30 60 90 sin 120 is equal to sqrt 3 over 2. The exact value of is. Ex 2 2 16 find the values of sin 1 sin 2π 3 let y sin 1 sin 2𝜋 3 sin y sin 2𝜋 3 sin y sin 120 but range of principal value of sin 1 is π 2 π 2 i e.

The derivative of the sine is equal to cos x. 120 degrees is located in the second quadrant in which the terminal angle equivalent is 60 degrees. Apply the reference angle by finding the angle with equivalent trig values in the first quadrant.

Sin 2pi 3 sin pi pi 3 sin pi cos pi 3 cos pi sin pi 3 since sin pi 0 and cos pi 1 this equals. Free pre algebra algebra trigonometry calculus geometry statistics and chemistry calculators step by step. Evaluate sin 2pi 3 get the answer to this question and access a vast question bank that is tailored for students.

The sine function is an odd function for every real x sin x sin x. Pi is equal to 180 hence 2pi 3 is equal to 120 degrees. Properties of the sine function.
