(sinx-cosx)(sinx+cosx) Factorizing this algebraic expression is based on this property: a^2 - b^2 =(a - b)(a + b) Taking sin^2x =a and cos^2x=b we have : sin^4x-cos^4x=(sin^2x)^2-(cos^2x)^2=a^2-b^2 Applying the above property we have: (sin^2x)^2-(cos^2x)^2=(sin^2x-cos^2x)(sin^2x+cos^2x) Applying the same property onsin^2x-cos^2x thus, (sin^2x)^2-(cos^2x)^2 =(sinx-Cosx)(sinx+cosx)(sin^2x+cos^2x

New questions in Mathematics. Explain how you would make use of triangle Nov 05, 2018 · a) By considering De Moivre's Theorem with n=4 and n=2, express cos 4 x in the form: cos 4 x = Acos(4x) + Bcos(2x) + C, where A, B and C are constants which you should determine. b) Derive a similar expression, also in terms of cos(4x) and cos(2x), for sin 4 x. My current solution: Using the Theorem I have derived that: cos(2x) = cos 2 x - sin 2 x Nov 11, 2007 · Well done if you get this one it's hard I think you have to start by 'pretending' that sin^4x + cos^4x is sin^2x + cos^2x and use sin^2x + cos^2x = 1 Then you have to do something with double angle formulae maybe Jan 05, 2019 · `=4[x-cos^2x]^3[1+` `{:2 sin x cos x]` 4.

Derivate of above gives you this below result.

So I= - integ.(1-t^2)^3 × t^4 dt =Integ.(1–3t^2 + 3 t^4 -t Find the Derivative - d/dx cos(4x) Differentiate using the chain rule, which states that is where and . Tap for more steps To apply the Chain Rule, set as . We can verify that this is a c-derivative of this. It's going to be two cosine of two x, we have it right over there, plus 1/8 times sine of four x. Derivative of sine of four x is going to be four cosine of four x, which is exactly what we have there. And then home stretch, we just write the plus C, plus sub constant. This is an indefinite Derivative of 3sin(4x).
