Angle A equals 65 degrees. The side across from angle A is 5; what is the length of the side across from angle B, if the ratio of sin 75 to sin 65 is 213/200 and remembering to use the Law of Sines? ANSWER: _213/40_ (sin 65 / 5 = sin 75 / B, cross-multiply, B sin 65 = 5 sin 75, divide by sin 65, B = 5 * (sin 75/sin …

Consider what happens to the unit vectors . 1 0 and 0 1 when rotated CCW by angle θ: 1 0 gets sent to cos θ sin θ , and 0 1 gets sent to -sin θ cos θ . Therefore a vector . v 1 = v 1x v 1y gets sent to a new vector, v 2 = v 2x v 2y , where . v 2x v 2y = v 1 cos θ - v 2 sin θ v 1 cos θ + v 2 sin θ . We can write this transformation of ...
