What is the cosine of 90 degrees?
Cosine(90) = 0 NB Cosine(0) = 1 Cos(30) = 0.8669... Cos(45) = 0.7071... Cos(60) = 0.5 Cos(90) = 0 Cos(120) = -0.5 Cos(0135) = -0.7071... Cos(150) = -0.8660... Cos(180) = -1 NB #1 ; refer to your (scientific) calculator or #2 ; refer to Castles Four Figures Tables. NNB Note the negatives (-) between 90 & 180.
The hypotenuse of a 30-60-90 triangle measures 2 feet how long is the short leg of the triangle?
Using the cosine ratio: 2*cos(60) = 1 Answer: 1 foot
If tan is square root of 3 what is cos?
tan θ = √3. tan-1(√3) = π/3 radians or 4π/3 radians, in degrees it would be 60° or 240° tan θ = sin θ / cos θ So, tan (π/3) = sin (π/3) / cos (π/3) = tan (4π/3) = sin (4π/3) / cos (4π/3) cos (π/3) = 1/2 cos (4π/3) = -1/2 Therefore cos θ = 1/2 or -1/2 when tan θ = √3
Why is sine 30 the same as cosine of 60?
sin(30) = sin(90 - 60) = sin(90)*cos(60) - cos(90)*sin(60) = 1*cos(60) - 0*sin(60) = cos(60).
What is 7 x 60 x cos 60 equals?
cos(60) = 0.57 x 60 x cos(60) = 7 x 30 = 210
What is cos 60 degrees?

What is the cos 60 degrees?
I can answer if you tell me what cos means.
What is the tangent of 60 degrees?
Tan(60) = Sin(60)/ Cos(60) Sin(60) = sqrt(3)/2 Cos(60) = 1/2 Hence Sin(60) / Cos(60) = [sqrt(3) / 2] / [1/2} => sqrt(3) / 2 X 2/1 sqrt(3) Hence Tan(60) = sqrt(3) = Numerically = 1.732050808....
Cos 195 degree use the trigonometry functions of quadrantal angles and special to find the exact value?
cos(195) = cos(180 + 15) = cos(180)*cos(15) - sin(180)*sin(15) = -1*cos(15) - 0*sim(15) = -cos(15) = -cos(60 - 45) = -[cos(60)*cos(45) + sin(60)*sin(45)] = -(1/2)*sqrt(2)/2 - sqrt(3)/2*sqrt(2)/2 = - 1/4*sqrt(2)*(1 + sqrt3) or -1/4*[sqrt(2) + sqrt(6)]
What is the cofunction of sin 30 degree?
cos 60
What is a quadrantal angle?
A Quadrantal angle is an angle that is not in Quadrant I. Consider angle 120. You want to find cos(120) . 120 lies in quadrant II. Also, 120=180-60. So, it is enough to find cos(60) and put the proper sign. cos(60)=1/2. Cosine is negative in quadrant II, Therefore, cos(120) = -1/2.

How do you use calculator to find cos degrees?
To find the cosine of an angle in degrees using a calculator, first ensure that the calculator is set to degree mode (not radians). Enter the angle in degrees, then press the "cos" button. The calculator will display the cosine value for that angle. For example, to find cos(60°), input 60, select "cos," and the result will be 0.5.
