WebFeb 14, 2016 · For something like $47^\circ$, you know that $\sin45^\circ =\dfrac1{\sqrt2}\approx0.7071$ and this is $2^\circ$ more than that. The rate of change of the sine-in-radians at that point is the cosine at that point, and the cosine of $45^\circ$ is also $\frac 1 {\sqrt 2}\approx0.7071$, so multiply by $\pi/180^\circ$ to get the rate of … WebVarious methods to find value of. sin. 18. ∘. To find value of sin 18 ∘. Now my textbook gives a proof in which it takes θ = 18 ∘ and then multiply it out by 5 and write again as sum of 2 θ + 3 θ and then taking sin on both sides forms a quadratic equation. porsche dealers in surrey
