Evaluate the integral. (remember to use absolute values where appropriate. Use c for the constant of integration.) 5 cot5(θ) sin

ozzi

$I=5\int \frac{cos^{4}\theta }{sin\theta }\times cos\theta d\theta \\\\I=5\int \left ( 1-sin^{2}\theta \right )^{2}\times \frac{cos\theta }{sin\theta }d\theta \\put\ \sin\theta =t\\\\dt=cos\theta d\theta \\\\I=5\int\frac{t^{4}+1-2t^{2}}{t}dt\ \ \ \ \ \ \ \ \ \ \because (a-b)^2=a^2+b^2-2ab\\\\I=5\left ( \int t^{3}dt + \int \frac{1}{t} -2\int t \right )dt$

by using the integration formula

we get,

$\\I=5\left ( \frac{t^{4}}{4} +logt -t^{2}\right )\\\\I=\frac{5}{4}t^{4}+5\log t-5t^{2}+c$

now put the value of t=\sin\theta in the above equation

we get,

$\int 5\cot^5\theta \sin^4\theta d\theta=\frac{5}{4}sin^{4}\theta+5\log \sin\theta - 5sin^{2} \theta+c$

hence proved

Write the equation of the parabola in vertex form.<br> vertex (3,1), point (2, - 6)<br> f(x) =?

Romashka [77]

Answer:

$f(x)=-7(x-3)^2+1$

Step-by-step explanation:

Vertex form of a quadratic is given by:

$f(x)=a(x-h)^2+k$

Where (h, k) is the vertex and <em>a</em> is the leading coefficient.

We are given that the vertex is (3, 1). Hence, <em>h</em> = 3 and <em>k </em>= 1. By substitution:

$f(x)=a(x-3)^2+1$

We are also given a point (2, -6). This means that when <em>x </em>= 2, <em>f(x)</em> = -6. Hence:

$-6=a((2)-3)^2+1$

Solve for <em>a</em>. Subtract:

$-6=a(-1)^2+1$

Simplify:

$-6=a+1$

Therefore:

$a=-7$

Hence, our quadratic is:

$f(x) = -7 (x-3)^2 + 1$
