Q2. Verify that the given function is a solution of the differential equation. (1) $y' + y = 0$; $y = 3e^{-x}$ (2) $\frac{d^2y}{dx^2} + 4y = 0$; $y = c_1 \sin 2x + c_2 \cos 2x$ (3) $y' + 2xy^2 = 0$; $y = \frac{1}{4 + x^2}$ (4) $\frac{\partial w}{\partial t} = \frac{\partial^2 w}{\partial x^2}$; $w(x, t) = x^3 + 6xt$ Q3. Solve the given problems (1) $\frac{dy}{dx} - 2xy^2 = 0$; $y(1) = -2$ (2) $y' = 2x - \cos x$ (3) $y = \frac{x}{x^2 + 1}$ (4) $\frac{dy}{dx} + \frac{3}{x}y = x^2$; $y(1) = 1/2$ (5) $\frac{d^2x}{dt^2} - 2t - 2 = 0$ [Hint: You may need to integrate twice] (6) $xy' + y = e^x$; $y(1) = 2$ (7) $\frac{dy}{dt} + 3t^2 = 6t^2$ (8) $x^2y' = -3xy + 6$ (9) $x^5 \frac{dy}{dx} + 4xy = 7$ (10) $y' = xy^2 - 2xy$; $y(0) = 1$

Consider the function $f(x) = 5x^2 - 9$. (a) Simplify the following difference quotient as much as possible $\frac{f(3+h) - f(3)}{h} = 5h + 30$ (b) Use your result from (a) and the limit definition of the derivative to calculate $f'(3) = \lim_{h \to 0} \frac{f(3+h) - f(3)}{h} = 30$ (c) Use your answer from part (b) to find the equation of the tangent line to the curve at the point $(3, f(3))$. y = 30x + 60
