**Given sin(theta)= 7/11 and sec(theta)<0 Find cos(theta**

find sin theta and cos theta if the terminal side of theta lies along the line y=2xs in Quadrant 3? Draw the angle 225 degrees in standard position, and then locate a convenient point on the terminal side of …... \[\tan \theta = \frac{\sin \theta}{\cos \theta}.\] You can check that the two definitions of the tangent are equivalent. For angles that have measure larger than $90$ degrees or measure smaller than $0,$ that is with a negative measure, the definitions are more convoluted.

**Find tan theta given that sin theta =4/5 and cos theta**

12/05/2008 · Best Answer: Cos theta = adjacent / hypotenuse So when cos theta = 0.47, take the adjacent as 0.47 and the hypotenuse as 1. The opposite side is therefore sqrt(1^2-0.47^2) = 0.883... 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.

14/08/2016 · If sin $ \displaystyle \theta$ =$ \displaystyle \frac{4}{5}$ , find cos $ \displaystyle \theta$ and tan $ \displaystyle \theta$ Can you help me to solve.... 11/07/2008 · if csc theta = 3 and sec theta = 3 sqrt 2 / 4 find sin theta, tan theta and cos squared theta. I know that sin theta = 1/csc theta = 1/3, but unsure how to find tan theta or cos squared theta.

**How do you find the exact values of sin(theta/2) cos**

find sin theta and cos theta if the terminal side of theta lies along the line y=2xs in Quadrant 3? Draw the angle 225 degrees in standard position, and then locate a convenient point on the terminal side of …... 11/07/2008 · if csc theta = 3 and sec theta = 3 sqrt 2 / 4 find sin theta, tan theta and cos squared theta.

## How To Find Theta Tan Cos And Sin

### 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

- 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
