22/07/2010 · Best Answer: sin = opposite/hypontenuse. In this case, the vertical leg terminates at -5 and the length of the hypotenuse is 6. The length of the horizontal leg will be sqrt[36-25] = sqrt(11) tangent = opposite/adjacent = -5/sqrt(11)... 22/07/2010 · Best Answer: sin = opposite/hypontenuse.

Unit Circle . The "Unit Circle" is a circle with a radius of 1. Being so simple, it is a great way to learn and talk about lengths and angles. The center is put on a graph where the x axis and y axis cross, so we get this neat arrangement here. Sine, Cosine and Tangent. Because the radius is 1, we can directly measure sine, cosine and tangent. What happens when the angle, ?, is 0°? cos 0... Definitions: In the following definitions, sine is called “sin,” cosine is called “cos” and tangent is called “tan.” The origin of these terms relates to arcs and tangents to a circle. The origin of these terms relates to arcs and tangents to a circle.

## How To Find Theta Tan Cos And Sin

3/12/2007 · NOTE: the previous ANSWERS that say SINA = 7 and COSA = 25 ARE TOTALLY wrong. Reason is that SIN and COS CAN NEVER be greater than ONE or less than NEGATIVE one.

- That means that the sine of angle A is sin A = a/c. What you do with that depends on what you know and what you want to find out. There are three pieces of information in that equation: the angle A, the side length a, and the hypotenuse c. Essentially, if you know any two of them, you can find the third that you don't know.

- Given: sin theta = -4/5 cos theta >0 Since sin is negative and cos is positive, theta lies in the 4th quadrant. All trigonometric ratios, except cos and sec are negative in the fourth quadrant.
- 21/07/2010 · your qn floored me on the initiating - attempt squaring the two factors (in case you spot a squareroot attempt, this would simplify issues) in the present day you get: ( if c = cos theta, s = sin theta) c^2 + 2cs + s^2 = 2c^2 or c^2 - s^2 = 2cs now think of one million/2 angles.... the lhs (left hand area) is comparable to cos(2.theta) the rhs is comparable to sin(2.theta) Now sin(2.theta
