The cotangent function (cot(x)), is the reciprocal of the tangent function.cot(x) = cos(x) / sin(x)Trig Table of Common Angles; angle (degrees) 0 30 45 60 90 120 135 150 180 210 225 240 270 300 315 330 360 = 0; angle (radians) 0 PI/6 PI/4 PI/3 PI/2The value of sin 3pi/4 in decimal is 0.707106781. . .. Sin 3pi/4 can also be expressed using the equivalent of the given angle (3pi/4) in degrees (135°). We know, using radian to degree conversion, θ in degrees = θ in radians × (180°/pi) ⇒ 3pi/4 radians = 3pi/4 × (180°/pi) = 135° or 135 degrees ∴ sin 3pi/4 = sin 3π/4 = sin(135 ...In addition to degrees, the measure of an angle can be described in radians. See Example. To convert between degrees and radians, use the proportion $\frac{θ}{180}=\frac{θ^R}{π}$. See Example and Example. Two angles that have the same terminal side are called coterminal angles. We can find coterminal angles by adding or subtracting 360 ...Sine and cosine are the fundamental trigonometric functions arising from the previous diagram:. The sine of theta (sin θ) is the hypotenuse's vertical projection (green line); andThe cosine of theta (cos θ) is the hypotenuse's horizontal projection (blue line).We can rotate the radial line through the four quadrants and obtain the values of the trig … (Note: "Degree" is also used for Temperature, but here we talk about Angles) The Degree Symbol ° We use a little circle ° following the number to mean degrees. For example 90° means 90 degrees. One Degree. This is how large 1 Degree is. The Full Circle. A Full Circle is 360° Half a circle is 180° (called a Straight Angle) Quarter of a ... cos (225°) cos ( 225 °) Apply the reference angle by finding the angle with equivalent trig values in the first quadrant. Make the expression negative because cosine is negative in the third quadrant. −cos(45) - cos ( 45) The exact value of cos(45) cos ( 45) is √2 2 2 2. − √2 2 - 2 2. The result can be shown in multiple forms..
