Answer:
-16.8
Step-by-step explanation:
split 5.6 into two numbers, 5 and 0.6.
5 x -3 = -15
0.6 x -3 = -1.8
add together: -15 + -1.8 = -16.8
About 7
because 5^2+5^2 is 50 and then you take the sq root of 50 which is about 7
Answer:
Step-by-step explanation:
Its 5
Answer:
1) - 2 / (cos x + sinx)^2.
Step-by-step explanation:
1) I assume you want the derivative of (cos x - sin x) / ( cos x + sin x).
y' = (cosx + sinx)( -sinx - cosx) - (cosx - sinx)(-sinx + cosx)
---------------------------------------------------------------------------
(cosx + sinx)^2
= -sinxcosx - cos^2x - sin^2x - sinxcosx - (-sinxcosx+cos^2x+sin^2x-sinxcosx
-------------------------------------------------------------------------------------------------------
(cosx + sinx)^2
= -2sinxcosx - 1 - ( -2sinxcosx + 1 ) / (cosx + sinx)^2
= -2sinxcosx - 1 - ( -2sinxcosx + 1 ) / (cosx + sinx)^2
= - 2 / (cos x + sinx)^2.
