Sin 210 Degrees

Sin 210 Degrees

Should I use a calculator to estimate the sin at 210 degrees? Have I done this before? 3

Sin 210 = 360 150

= Sin 150

I stand there

The answer is 2 out of 1

Hello,

I want to answer your question.

Share some tips.

1. NAS (90A) = COS (A)

2. NAS (90 + A) = COS (A)

3. NAS (180A) = NAS (A)

4. NAS (180 + A) = NAS (A)

5. SIN (270A) = COS (A)

6. NAS (270 + A) = COS (A)

7. NAS (360A) = NAS (A)

8. NAS (360 + A) = NAS (A)

You may have noticed that sin becomes a cos when it first occurs.

The term in brackets is 90 or 270. You are right

As long as the first term is an odd multiplication of 90, there is no change.

In the coast and vice versa. In addition, the tan becomes a cradle and

Dry in Cosec.

But if the first term is 180 or a multiple of it, nothing changes.

The second point is the signal. It depends on the quadrant. Sin is positive

Negative in Quadrants I and II and negative in Quadrants III and IV. There it can be seen that only 1, 2, 3 are positive and the rest are negative, except 8 which are in quadrant I.

Thanks for being patient with it. Come now

For your question,

210 = 180 + 30

NAS (210) = NAS (180 + 30)

= NAS (30)

= (1/2)

Where

210 = 270 60

NAS (210) = NAS (270 60)

= KOS (60)

= (1/2)

Just that.

Sin 210

Cse, which gives a sharp angle near the x axis. 180 in this case

(210180) = (30)

This is the third quadrant where x and y are ()

He is here

Sin 210 = Sin 30

= y / hour because y = ()

= 1/2 *** Answer

Note the following:

(Legs and hyphens 30 degree triangle

x: y: h = square (3): 1: 2)

Sin (210) = Sin (180 + 30) = Sin 180 cos 30 + cos 180 sin 30 = 0 + (1/2) = 1/2
