( (sin)(2⋅ 150))Multiply( 2) by ( 150).( (sin)(300))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 fourth quadrant.( -(sin)(60))The exact value of ( (sin)(60)...
This gives us the following value of sin 3°: or other forms depending how you factor the above. sin 6°:Using the above, one can compute the sine of 6 degrees finally as sine of twice 3 degrees to arrive at sin 18° and sin 72°:Taking the equivalent sine and cosine values of 1...
$$\mathrm{sin}(2x)\neq 2\mathrm{sin}(x) $$ Trigonometric functions are just more complicated than that. There is an identity for the sine of twice and angle. Here it is: $$\mathrm{sin}(2x)=2\mathrm{sin}(x)\mathrm{cos}(x) $$ ...
