Find the equation (in terms of {eq}x {/eq} and {eq}y {/eq}) of the tangent line to the curve {eq}r = 4 \sin 2 \theta {/eq} at {eq}\theta = \dfrac \pi6 {/eq}. Equation of the Tangent: Let {eq}r = f(\theta) {/eq} be the...
dy/dx = ky dy/y = kdx ln(y) = kx+C y = e^(kx+C)y = Ce^(kx)y(0) = 1 Ce^(k*0) = 1 C = 1 所以y = e^(kx)

Express y in terms of x from the following equation. 3x - 2y + 6 = 0 and check whether (-(5)/(2), - (3)/(4)) is a point on the given line.
For the first of the above integrals Bx=y2 is evaluated for y=0 and therefore vanishes; for the third integral By=-x2 is zero and that integral also vanishes. We can rewrite the second integral entirely in terms of y if we note that dx=-dy and that By=-x2=-(1-y)2. The line...
