Expressing sin (x±y) and cos (x±y) in terms of sinx, siny, cosx & cosy and their simple application Cos (x + y) × cos y + sin (x + y) × sin y = cos x Firstly, we will be using the trigonometric identities. 2019-11-30 · Misc 17 Find the derivative of the following functions (it is to be understood that a, b, c, d, p, q, r and s are fixed non-zero constants and m and n are integers 2019-11-30 · Transcript. Example 22 Find the derivative of (i) (x^5 − cos⁡x)/sin⁡x Let f(x) = (x^5 − cos⁡x)/sin⁡x Let u = x5 – cos x & v = sin x So, f(x) = (𝑢/𝑣) ∴ f’(x) = (𝑢/𝑣)^′ Using quotient rule f’(x) = (𝑢^′ 𝑣 −〖 𝑣〗^′ 𝑢)/𝑣^2 Finding u’ & v’ u = x5 – cos x u’ = 5. x5 – 1 – ( – sin x) = 5x4 + sin x v = sin x v’ = cos x Now, f Svenska: ·(matematik, till en funktion f) funktion F sådan att f är dess derivata En primitiv till cos är sin.··inte utvecklad, enkel Så oerhört primitivt!
