cos (2x)cos (x)+2cos (x)sin^2 (x)=1. Recall that. sin^2 (x)+cos^2 (x)=1. Solving for sin^2 (x) gives. sin^2 (x)=1-cos^2 (x) Apply this to the instance of sin^2 (x) in the equation: cos (2x)cos (x)+2cos (x) (1-cos^2 (x))=1. Distribute 2cos (x) through: cos (2x)cos (x)+2cos (x)-2cos^3 (x)=1.

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’ (x) How to show $$\sin(x+iy)=\sin(x) \cosh(y) + i\cos(x) \sinh(y)$$ I begin with $$\sin(x+iy) = \frac{e^{x+iy}-e^{-x-iy}}{2i} = \frac{e^xe^{iy}-e^{-x}e^{-iy}}{2i cos(90-x)=sin(x) Related TI Nspire file.

Affiliate. Notice how a "co- (something)" trig ratio is always the reciprocal of some "non-co" ratio. cos(x)sin(x) = sin(2x)/2 So we have cos(x)sin(x) If we multiply it by two we have 2cos(x)sin(x) Which we can say it's a sum cos(x)sin(x)+sin(x)cos(x) Which is the double angle formula of the sine cos(x)sin(x)+sin(x)cos(x)=sin(2x) But since we multiplied by 2 early on to get to that, we need to divide by two to make the equality, so cos(x)sin(x) = sin(2x)/2 sin ^2 (x) + cos ^2 (x) = 1 .

22. SOD. 2. (7) sin x + sin y = 2 Recall derivative function ratio rule g(x)=f(x)/h(x) ⇒ g'(x)=[f '(x)*h(x)-f(x)*h'(x)]/h²(x) In our case f(x)=sinx ⇒ f '(x)=cosx h(x)=x² ⇒ h'(x)=2x hence Hi,. in CAS why not we get cos (x) ² + sin (x) ² = 1 and can we linearize the simplest forms of trigonometric forms as cos (2x) or sin (2x) Best regards,.
