Webtan(9x−1)dx Let u = 9x−1 then du dx = 9 and dx = du 9 ∴ Z tan(9x−1)dx = Z tanu· du 9 = 1 9 Z tanudu = − 1 9 ln cosu +C = − 1 9 ln cos(9x−1) +C . Note. The final result can also be … Web∘ ) = cos ( A ∘ ) , then A = degrees. (b) If cos2 ( 9 x ) − sin2 ( 9 x ) = cos ( B ) , then B = . VIDEO ANSWER:So in this question, in a part of it is given that of course is square off. 23° sign is square of 23° is equal to the cost of air degree. …
If A + B =90∘, then, cos A ·cosec B cos A ·sin B =A. cos 2 AB. cos …
WebLet B = 2 sin2 x - cos 2x, then (A) - 1 le B le 3 (B) 0 le B le 2 (C) - 1 le B le 1 (D) - 2 le B le 2 . Check Answer and Solution for above question f Tardigrade Web9 jul. 2024 · Then multiply by the equality for cos 2 x, so: cos 2 x * sin 4 x = 1/2 (1 - cos2x) * (3/8 + 1/2 (cos2x) - 1/8 (cos4x)) Expand the right hand side, which will once again give a term including cos 2 2x, which will need to be converted as before. When you finish expanding and simplifying, I think this will result in an equation of the form given. is the old testament done away with
