It depends if 1 plus tan theta is divided or multiplied by 1 minus tan theta.
Using x instead of theta, cos2x/cosec2x + cos4x = cos2x*sin2x + cos4x = cos2x*(sin2x + cos2x) = cos2x*1 = cos2x
I'm asuming you meant "ten theta"the square of 5 is 2525 divided by 10 is 2.5so theta equals 2.5there you go =)
Zero. Anything minus itself is zero.
cosine (90- theta) = sine (theta)
Yes. (Theta in radians, and then approximately, not exactly.)
sin(theta) = 15/17, cosec(theta) = 17/15 cos(theta) = -8/17, sec(theta) = -17/8 cotan(theta) = -8/15 theta = 2.0608 radians.
theta = arcsin(0.0138) is the principal value.
sin (theta) = [13* sin (32o)]/8 = 13*0.529919264/8 = 0.861118804 [theta] = sin-1 (0.861118804) [theta] = 59.44o
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).
Cotan(theta) is the reciprocal of the tan(theta). So, cot(theta) = 1/2.
The answer depends on what theta is and the units of its measurement.
If sine theta is 0.28, then theta is 16.26 degrees. Cosine 2 theta, then, is 0.8432
If r-squared = theta then r = Â±sqrt(theta)
It is a mathematical expression.
Tangent (theta) is defined as sine (theta) divided by cosine (theta). In a right triangle, it is also defined as opposite (Y) divided by adjacent (X).
You will have to bear with the angle being represented by x because this browser will not allow characters from other alphabets!sin^2x + cos^2x = 1=> sin^2x = 1 - cos^x = (1 + cosx)(1 - cosx)Divide both sides by sinx (assuming that sinx is not zero).=> sinx = (1 + cosx)(1 - cosx)/sinxDivide both sides by (1 - cosx)=> sinx/(1 - cosx) = (1 + cosx)/sinx=> sinx/(1 - cosx) - (1 + cosx)/sinx = 0
It is a trigonometric equation.
There is no easy simplification.
cos2(theta) = 1 so cos(theta) = Â±1 cos(theta) = -1 => theta = pi cos(theta) = 1 => theta = 0
cos2(theta) = 1 cos2(theta) + sin2(theta) = 1 so sin2(theta) = 0 cos(2*theta) = cos2(theta) - sin2(theta) = 1 - 0 = 1
d theta divided by 4.28 is not an equation or inequality: it is an expression. An expression cannot be solved.
If sin (theta) is 3/5, then sin2 (theta) is (3/5)2, or 9/25.
The side adjacent to theta divided by the hypotenuse, or the angle opposite of the right angle
If sin(theta) is 0.9, then theta is about 64 degrees or about 116 degrees.
