# What is Cos 40 degrees? - Research Maniacs.

Use our cosx calculator to find the cosine of -40 degrees - cos-40 ° - or the cosine of any angle in degrees and in radians. Calculate value of Sin, Cos, Tan, Cot, Cosec, Sec, Sinh, Cosh, Tanh, Coth, Cosech, Sech, Asin, Acos, ATan, ACot, ACosec, ASec and other trigonometry function. Since our angle is between 0 and 90 degrees, it is located in Quadrant I In the first quadrant, the values for sin, cos and tan are positive. Determine angle type: 40 is an acute angle since it is less than 90° cos40 = 0.76604444363175 In Microsoft Excel or Google Sheets, you write this function as =COSRADIANS40. In degree mode. cos40 = 0.7660444431 degrees 77 degrees will do In radians. cos40 = - 0.6669380617 radians Asked in School Subjects, Math and Arithmetic, Trigonometry What is the cosine of 90 degrees? The cosine of 90 degrees is zero. Asked in Trigonometry.

Question 609772: The expression cos^2 40 degrees - sin^2 40 degrees has the same value as 1 sin 20 degrees 2 sin80 degrees 3 cos 80 degrees 4 cos 20 degrees. I do not know how to go about this question.all I know is this identity sin^2 thetacos^2 theta = 1, but I do not know how to apply it. When we covert degrees into radians, we use the conversion factor. pi/180 Notice that what we want, radians, is in the numerator. We multiply this by 40 degrees to get. What is value of sin 30? What about cos 0? and sin 0? How do we remember them? Let's learn how. We will discuss what are different values of sin, cos, tan, cosec, sec, cot at 0, 30, 45, 60 and 90 degrees and how to memorise them. The cosine of 30 degrees is 0.86. It is also expressed as the square root of three divided by two. The cosine of an angle is calculated by dividing the length of the side of a right triangle adjacent to the acute angle by the length of the hypotenuse.
