In a sector of angle #theta# (in radians), ends of chord are joined to form a triangle and segment. If areas of triangle and segment are equal, then what is the ratio #p# of the angle to its sine ratio?

How do you write in simplest radical form the coordinates of point A if A is on the terminal side of angle in standard position whose degree measure is #theta#: OA=9, #theta=150^circ#?

Questions and Videos on Converting Equations from Polar to Rectangular, within Precalculus

Dec 19, 2017 · We can only use the relation theta=arctan(y/x). The relation between Cartesian or rectangular coordinates (x,y) and polar coordinates (r,theta) is given by x=rcostheta and …

The answer is f (theta)=e^ (theta) (and f (theta)=e^ (-theta), depending on how you decide to measure the angle, see below). You can think about this in terms of dot products of …

Explanation: We are going to apply the static equilibrium conditions (translational equilibrium + rotational equilibrium) to both bars separately.

Q1: =-sqrt(4-x^2)/x^2 - sin^-1(x/2) + C Integrals can be solved in many ways, but for these I'll be using trig-substitution for Q1 and partial fractions for Q2. Q1: intsqrt(4-x^2)/(x^2)dx For this, we …

How do you integrate ∫ 1 √3x − 12√x + 53 using trigonometric substitution?

Explanation: We have to prove, #tan theta/ (1-cot theta) + cot theta/ (1-tan theta) = 1+tan theta+ cot theta#

(d theta)/dt = 3/25" rad/s" Using the chain rule: (dh)/dt = (dh)/ (d theta) (d theta)/dt Solving for (d theta)/dt: (d theta)/dt = ( (dh)/dt)/ ( (dh)/ (d theta))" [1 ...
