∫ e^(-4x) dx over the interval [ 0 , 1 ]
¼ - 1/(4e⁴)
∫sinx dx over the interval [ 0 , Π/4 ]
-√2 / 2 +1
∫ x² cos (x³) dx
1/3 sin (x³) + C
if f(x) = ln ( x + 4 + e^(-3x) ) then f'(0)=
d/dx x² sin(2x)
2x ( sin(2x) + x cos(2x) )
f'(x)=x² - 2/x then f is decreasing
( 0 , 2^(1/3)
If the line tangent to the graph of the function f at the point ( 1 , 7 ) passes through the point ( -2 , -2 ) then f'(1)=
f = 2x e^x then f is concave down when
( -∞, -2 )
y'=2x+3. Find the equation for y if it passes through the point ( 1 , 2 )
f = 4x³-5x+3. Find the equation for the tangent line to the graph of f at x=-1
y = 7x + 11
