wat is the solution for sinx-cosx=2 ? whats the appropriate unit of measure for -5 1/4in - 2 2/3 in (sinx+cosx)^2 + (sinx-cosx)^2

(sin-cos)(sin+cos) help!! (sinX-cosX)(sinX+cosX) =(sin^2 - Cos^2X) =Sin^2X - (1-Sin^2X) =Sin^2X -1 + Sin^2X =2Sin^2X -1 Zulfikar Ali [email protected] 9899780221

sin x cos x = -1/2 solve for x sin x cos x = -1/2 solve for x sin x cos x = -1/2 => 2sinx cosx = -1 => sin(2x) = -1 => 2x = (3pi)/2 OR 2x = 270° => x = 3pi/4 OR x = 135°

does (sinx)^6 + (cosx)^6 = 1 ? like sinx^2 + cosx^2 = 1? no the answer is not equal to 1

...cosx=2 and cosx= 1/2? where do i go from here if this is even right the solution you got is correct it is cos X =2 and cos X =1/2 but we know maximum value of cosX is 1.so we discard the solution cos ...

...2)=sinx/1+cosx to solve for the value of tan45 degrees solve for tan45 degrees using the identity tan(x/2)=sinx/1+cosx tan(x/2)=sin(x)/(1+cos(x)) Setting x/2=45, means that x=90 (degrees) But ...

...cosx) The derivative of sin(cos(x)) dx is cos(cos(x))-sin(x). Unfortunately the fx-9850GII doesn't do symbolic differentiation so you'll have to get this result some other way. I cheated and used a ...

cosx) The 9750GII doesn't have symbolic capabilities so it can't give you a symbolic answer for this. It can evaluate it numerically at any point. The derivative of sin(cos(x) dx is cos(cos(x))-sin(x)
