Cos 1/2 Value In Degree
Word problems on sum of the angles of a triangle is 180 degree. 10 is an acute angle since it is less than 90.
How Do You Evaluate Cos 1 1 2 Socratic
Make the expression negative because cosine is negative in the second quadrant.
Cos 1/2 value in degree. The cosine of a 90 degree angle is equal to zero since in order to calculate it we would need a triangle with two 90 degree angles which is the definition of a straight line. The trignometric table of sin cos tan cosec sec cot is useful to learn the common angles of trigonometrical ratios from 0 to 360. Then x cos 1 1 2 therefore x 60 degrees 300 degrees where x is greater than or equal to 0 and lesser than or equal to 360 or pi 3 radians 5pi 3 radians where x is greater than or equal to 0 and lesser than or equal to 2pi.
If cos x 1 2. 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. Since cos α b c from this definition it follows that the cosine of any angle is always less than or equal to one and it can take negative values.
