sin^2(x) + cos^2(x) = 1 (the other identities are easily derived from this). So most functions with some trig function can be solved using these 2 sets of identities? This function popped up towards the end of my derivatives chapter, and the book on trig barely covered those identities at all! :( (it mentioned the sin(a+b) identity but never used it).

If we instead apply the linear approximation method and plug in sin x ≈ x, we get: sin x x x2 ≈ x2 1 ≈ . x We then conclude that: sin x lim = x 0+ x2 ∞ → sin x Integral of (Sin^-1 x)^2 dx by PartsWatch more videos at https://www.tutorialspoint.com/videotutorials/index.htmLecture By: Er. Ridhi Arora, Tutorials Point Answer: 30° and 150° Explanation: The equation is sin x = 1/2 and we look for all solutions lying in the interval 0° ≤ x ≤ 360°. This means we are looking for all the angles, x, in this interval which have a sine of 1/2. We begin by sketching a gr Answer to: Find the derivative of m(x) = x^2 sin (x).
