Sin (theta) can most easily be found on a scientific calculator. You can also approximate it with Taylor's Series...
sin(x) = SummationN=0toInfinity (-1N / (2N + 1) !) (x(2N+1)))
sin(x) = x - x3/3! + x5/5! - x7/7! + ...
Using only the four terms above, you can approximate sin(x) within about 0.000003 in the interval x = [-1, +1].

If costheta -.444 with theta in quadrant 2 find sintheta?
Since theta is in the second quadrant, sin(theta) is positive. sin2(theta) = 1 - cos2(theta) = 0.803 So sin(theta) = +sqrt(0.803) = 0.896.
What is the sin theta of 30 degrees?
Sin theta of 30 degrees is1/2
How do you finish the equation sin 2 theta?
(/) = theta sin 2(/) = 2sin(/)cos(/)
If cos and theta 0.65 what is the value of sin and theta?
You can use the Pythagorean identity to solve this:(sin theta) squared + (cos theta) squared = 1.
How do you simplify sin theta times csc theta divided by tan theta?
Since sin(theta) = 1/cosec(theta) the first two terms simply camcel out and you are left with 1 divided by tan(theta), which is cot(theta).
If costheta -.444 with theta in quadrant 2 find sintheta?

What is sin theta cos theta?
It's 1/2 of sin(2 theta) .
What is the derivative of sin under root theta?
The derivative of (sin (theta))^.5 is (cos(theta))/(2sin(theta))
Find theta if theta is 0 deg theta 360 deg and 2 sin theta plus 1 equals 0?
2 sin (Θ) + 1 = 0sin (Θ) = -1/2Θ = 210°Θ = 330°
How do you find smallest positive value of theta to the nearest degree. When sin theta equals 0.3455?
you have to do the arcsin which is sin-1 on your calculator. i have not met anyone in my life who can do sin or arcsin in their head. not even my college teachers. your theta is equal to 20degrees
What does 2sin squared theta equal and why?
It is 2*sin(theta)*sin(theta) because that is how multiplication is defined!
What is the equivalent of sine theta over secant theta?
For such simplifications, it is usually convenient to convert any trigonometric function that is not sine or cosine, into sine or cosine. In this case, you have: sin theta / sec theta = sin theta / (1/cos theta) = sin theta cos theta.
How do you calculate Sin theta equals 13 times sin 32 degrees divided by 8?
sin (theta) = [13* sin (32o)]/8 = 13*0.529919264/8 = 0.861118804 [theta] = sin-1 (0.861118804) [theta] = 59.44o
De Morgan's law in complex number?
(Sin theta + cos theta)^n= sin n theta + cos n theta
What is the identity for tan theta?
The identity for tan(theta) is sin(theta)/cos(theta).
How do you solve 2 sin squared theta equals one fourth?
2 sin^2 theta = 1/4 sin^2 theta = 1/8 sin theta = sqrt(1/8) theta = arcsin(sqrt(1/8))
How do you simplify tan theta cos theta?
Remember that tan = sin/cos. So your expression is sin/cos times cos. That's sin(theta).
