If 3sinx + 4cosx = 5, then 4sinx - 3cosx =....??? 0 -5 1/5 5 plz expl ...
Web2 dec. 2024 · The answer is = 18 Explanation: We need sin2x +cos2x = 1 As, 3sinx +5cosx = 4 Then (3sinx + 5cosx)2 = 42 = 16 9sin2x + 25cos2x +30sinxcosx = 16 ......... (1) Let , (3cosx − 5sinx)2 = p Then 9cos2x + 25sin2x −30sinxcosx = p ............. (2) Adding equations (1) and (2) 9(sin2x + cos2x) + 25(sin2x +cos2x) = p +16 As the 30sinxcosx cancels … WebCorrect option is B) 5sinx+4cosx=3 Squaring both sides 25sin 2x+16cos 2x+2∗5∗4sinxcosx=9⇒9sin 2x+7+40sinxcosx=0 ⇒9sin 2x+7=−40sinxcosx Now, … hertz car rental louisville ky
If 3sinx + 4cosx = 5, what is the value of 4sinx - 3cosx
WebAnswer (1 of 2): As it is clear From the Graph,log2x is an increasing function,therfore value of given function will be maximum when 3Sinx-4Cosx +15/10 takes maximum value , which is when 3Sinx-4Cosx is maximum (as 15/10 is constant). Now,What remains to find is maximum of 3Sinx-4Cosx ,which can... Web3cos (x) = 5sin(x) 3 cos ( x) = 5 sin ( x) Divide each term in the equation by cos(x) cos ( x). 3cos(x) cos(x) = 5sin(x) cos(x) 3 cos ( x) cos ( x) = 5 sin ( x) cos ( x) Cancel the common … Websinx/cosx = 3/5 we know that sinx/cosx = tanx hence tanx= 3/5 x = tan^ (-1) [3/5] x = 0.5404 rad ~30.9° More answers below Gordon M.
