What are the 6 trig functions of 300 degrees?
sin 300= cos 300= tan 300= cot 300= sec 300= csc 300=
What’s the exact value of sin 60?
From the above equations, we get sin 60 degrees exact value as √3/2.
What quadrant is sin 300 degrees in?
b 300° lies in the fourth quadrant so sin 300° is negative. c 235° lies in the third quadrant so tan 235° is positive.
How do you solve SIN 300 degrees?
Complete Step by Step Solution: We know the value of sin(60∘). Therefore the answer is −√32. Second Method: We can say that sin(5π3)=sin(300) since the value of π is 180∘.
Why is sin 60 and sin 120 the same?
The value 120 degrees falls on the second quadrant. As the value of sine function in the second quadrant takes the positive value, the value of sin 120 degrees should be a positive value. By looking at the diagram given above, the value of sin 60 is equal to the value of sin 120. It means that, sin 60 = sin 120 = √3/2.
What is the exact value of sin 120 degrees?
Hence, the sin 120 degrees exact value is √32.
What is the formula of COS 120?
Value of Cos 120 is -½.
Is Cos 120 positive?
We know value of cosine of an angle in first and fourth quadrant is always positive. Think about 120° it is clear that 120° lies in second quadrant and -120° lies in fourth.
What is the formula of cos a minus Cos B?
= cosA cosB − sinA sinB cos(A − B)
What is the formula for cos a B?
(52) cos A cos B = ½ cos(A − B) + ½ cos(A + B) sin A sin B = ½ cos(A − B) − ½ cos(A + B)
What is Cos Alpha Beta?
We will learn step-by-step the proof of compound angle formula cos (α – β). Now we will prove that, cos (α – β) = cos α cos β + sin α sin β; where α and β are positive acute angles and α > β. Let a rotating line OX rotate about O in the anti-clockwise direction.
