Nov 26, 2015 · $\begingroup$ One might also be inclined to take a Fourier series, given that $\sin(\cos(x))$ is periodic. I just suggest this since that's a little more natural for a periodic function than Taylor expansion (though the coefficients are harder to compute; Mathematica insists they have a closed form in terms of the Bessel function though ...

Dec 2, 2014 · What is the integral of $\sin(\cos x)$ ? So glad you asked ! :-) Although the indefinite integral does not possess a closed form, its definite counterpart can be expressed in terms of certain special functions, such as Struve H and Bessel J.

Aug 28, 2016 · 1) $\cos^2 x + \sin^2 x = 1$ So $2 \cos^2 x = 1$ So $\cos x = \sin x = \pm \sqrt{\frac 12}$ 2) $\sin x$ is the adjacent side of a right triangle.

Aug 30, 2020 · Trigonometric Functions (And Functions In General) Aren't Considered As Operators, But As Functions Instead, So, Technically Speaking, They Can't Belong In The Order Of Operation (A.K.A. BODMAS/PEDMAS/BIDMAS).

Oct 14, 2018 · How can I know the values of: $\\sin(i)$ and $\\cos(i)$? I am studying complex variables for the first time, so I asked myself if these functions exist (considering that the complex plane can be seen...

May 3, 2017 · Many computational libraries contain a routine called sincos that allows one to compute sin and cos simultaneously. The existence of this routine suggests that calling this routine is more efficien...

Dec 1, 2015 · Drawing Sin Cos Tan Table. Step 5(orange):Once you have values for sine function, invert them for cosine i.e( sin 90 = cos 0, sin 60 = cos 30, sin 45 = cos 45 and so on) and you get values for cosine function. Step 6: For tangent, put sin/cos values and simplify. Step 7: You can extend the table for further angles by using formulas such as

Sep 18, 2015 · A simple way to do the indefinite integral is this $$ \int \underbrace{\sin(nx)}_{\displaystyle u} \Big(\underbrace{\cos(nx)\,dx}_{\dfrac{du} n}\Big) = \frac 1 n \int ...

Feb 14, 2019 · In pre-calc, we're doing trigonometric identities, and I have a question but my teacher isn't available right now. We have to verify trigonometric identities, but I can't progress right now becaus...
