What is the exact value of cos 240 degrees?
What is COS 120 in radians?
What is the exact value of sin 0?
Well, the point at ˚ is (1,) , and the y value here is . The hypotenuse, although measuring 1 unit, doesn’t matter, because a,a≠ , always equals , no matter the value of a . Hence, sin0˚= .
What is the exact value of tan 135?
How do you find COS 330?
- cos 330°=cos ( 360 -30)
- In fourth quad the value of cos A is positive .
- All angles when subtracted by multiple of 180° or (π) the function remain same .
- cos (30°)=√3/2.
What is the secant of 2pi 3?
What is Secant 2pi?
sec(x)=1cos(x) Thus, sec(π2)=1cos(π2) But since cos(π2) is zero, this division is not legit.
What is Secant equal to?
The secant of x is 1 divided by the cosine of x: sec x = 1 cos x , and the cosecant of x is defined to be 1 divided by the sine of x: csc x = 1 sin x .
What is the exact value of sin 180?
|θ||sin θ||cos θ|
What is the value of SEC Pi by 3?
What is the value of SEC Pi by 4?
The exact value of sec(π4) sec ( π 4 ) is 2√2 .
What is the COT of Pi 2?
The exact value of cot(π2) cot ( π 2 ) is 0 . Multiply −1 by 0 .
What is the cot of 300 degrees?
The cot of 300 degrees is -√(3)/3, the same as cot of 300 degrees in radians. To obtain 300 degrees in radian multiply 300° by / 180° = 5/3 . Cot 300degrees = cot (5/3 × .
