The answer is as follows.
Cosine of 40 degrees math. 3 40 120 x 40 3x 120 cos3x cos120 4c 3c 8c 6c 1 0 8c 6c 1 draw a graph of y 8x and y 6x 1 take the positive x value of the intersection point 0 77 cos40 which is positive. Using a table of cosines you can make calculations even if not at hand will be the scientific calculator. Cosine function along with sine and tangent is one of the three most common trigonometric functions. Cosine tables chart of the angle 0 to 90 for students.
What is cosine in mathematics. Sine cosine and tangent. Cos 40 0 7660444431 degrees 77 degrees will do in radians. Take cosx 0 77 0 75 a h o 3 4 7 sin40 7 4 tan40 7 3.
To find cos of another number please enter the number below and press calculate cos. 40 is an acute angle since it is less than 90 cos 40 0 76604444363175 write cos 40 in terms of sin since 40 is less than 90 we can express this in terms of a cofunction cos θ sin 90 θ cos 40 sin 90 40 cos 40 sin 50. For a given angle θ each ratio stays the same no matter how big or small the triangle is. Cos 40 0 6669380617 radians.
Here we answer one simple question. Sine cosine and tangent often shortened to sin cos and tan are each a ratio of sides of a right angled triangle. Cos 40 0 766044443119 this is the same answer you will get if you have a scientific calculator set to deg mode and then enter 40 followed by the cos button. Asked in school subjects math and arithmetic.
To find the cosine of the angle is sufficient to find the value in the table. Cos 40 0 6669380617 radians. Value of cos 40 radian 0 66693806. In the first quadrant the values for sin cos and tan are positive.
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. Cos 40 0 7660444431 degrees 77 degrees will do in radians. What is cos 40 degrees.
