If you have Cos theta equals 0.92568 How do you find theta in radians?

cos(t) = 0.92568
therefore t = cos-1(0.92568) = 0.3880.
If the answer comes out as 22.23, the calculator is set to degrees. Simply multiply that result by pi/180 to convert to radians (or reset the calculator to work in radians). Excel, for example, works in radians.
From that primary value you get
t = 0.3880 + 2*k*pi
and
t = 2*k*pi - 0.3880
for all integer values of k.

Find the four smallest positive numbers theta such that tangent theta equals -1 Write your answers in ascending order?
3*pi/4, 7*pi/4, 11*pi/4 and 15*pi/4 radians or2.3562, 5.4978, 8.6394 and 11.7810 radian (approx).
Find all angles in the interval 0 360 satisfying the equation cos theta equals 0.7902?
cos(theta) = 0.7902 arcos(0.7902) = theta = 38 degrees you find complimentary angles
How do you find the circumference of the earth using the arc length formula?
Just did this in my trig class yesterday. Arc length = radius * theta(radians) Circumference of Earth = radius of earth * 2pi Note: The arc length is the circumference of the Earth only in this case because theta is equal to 2pi.
How do you find theta if tan theta equals 1 and 0 is less than or equal to theta which is less than 2pi?
tan(theta) = 1 then theta = tan-1(1) + n*pi where n is an integer = pi/4 + n*pi or pi*(1/4 + n) Within the given range, this gives theta = pi/4 and 5*pi/4
How would you find possible values for theta if SECx equals 5pie divided by 4?
1.25
Should we find cos theta if sec theta equals -10?
No.
If tan Theta equals 2 with Theta in Quadrant 3 find cot Theta?
Cotan(theta) is the reciprocal of the tan(theta). So, cot(theta) = 1/2.
Find the four smallest positive numbers theta such that tangent theta equals -1 Write your answers in ascending order?
3*pi/4, 7*pi/4, 11*pi/4 and 15*pi/4 radians or2.3562, 5.4978, 8.6394 and 11.7810 radian (approx).
How do you find the sector area of a circle?
The area of a sector is 0.5*r^2*theta square units where r is the radius measured in linear units and theta is the angle (measured in radians).
How do you find tan-theta when sin-theta equals -0.5736 and cos-theta is greater than 0?
-0.5736
Is the theta in a projectile equation measured in degrees or radians?
The equations for projectiles shouldn't just have theta, they should have sin(theta) or cos(theta). As long as you have your calculator set in the right mode, either will work when you evaluate sin or cosine. Example: Say you have a projectile launched at 30 degrees above horizontal. In order to find the y velocity, you will have to calculate sin(30) with you calculator in degree mode. If instead you called this angle pi/6 (the same angle, just in radians), you could enter sin(pi/6) in your calculator in radians mode and get the same answer.
Find all angles in the interval 0 360 satisfying the equation cos theta equals 0.7902?

Find area of shaded sector?
theta (angle) _____ X pi r squared 360 Note that if the angle is measured in radians, then you only need to do Θ*r². A full circle is 360° or 2*pi radians
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°
If A equals B find alpha when theta equals 60 degree 90 degree?
You should supply more information.
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
How do you find the circumference of the earth using the arc length formula?
