**Sin 90**

### sin (90) = What is the price?

If theta is in degrees

Sin (90) = 1

When theta is in radians

90 radians = 90 x 3.14 / 180 degrees

= 1.57 degrees

Sin (1.57) = 0.893

Sin 90

Sin when your calculator is in degree mode (90) = 1.

But if your calculator is in radon mode, sin (90) = 0.8940 (4s.f.).

Since you want answers to triangular questions, the answers are correct in radon mode :)

Hasnain's answer is not well explained.

There was no point in trying to follow his words.

The declaration of sin (90) will say:

To find the value of sin (THETA), where angle THETA = 90,

It is important to know whether THETA (angle of presentation of Sintion)

There are two units of measurement which differ in degree or radian (?) And its means

And you also need to know if your sin expects a degree or a radiance.

In general, you can define the THETA unit on a calculator or using definitions.

Or, if you use a table of calculation values in the book,

Then the unit that should be THETA appears (degree or radon)

When using a table to find the value of the pocket (THETA).

With an understanding of the appropriate THETA units,

You can convert THETA from degree to radian using the following formula.

D degree = R radiance = D x (pi / 180) radians

For example, if D = 90 (ie degrees), then R = 90 x (3.14 / 180)

= 1.57 radians (ie 90 degrees)

Also, many calculators (standard on Windows computer systems) show:

sinr results when you use radon for THETA and.

The consequences of sin when you use degrees for THETA.

With this understanding of the THETA angle units,

This is the answer (or example) that Hasnain is trying to explain:

If THETA = 90 degrees, then sin (THETA) = sin (90) = 1 more

Because 90 degrees = 1.57 radians (defined in the following equation),

If THETA = 1.57 radians then sinr (THETA) = sinr (1.57) = 1 (0.793 step given by Hasnain).

Yes, according to THETA e units, sin (90) = sinr (1.57).

Depending on what sin expects from this unit of measure.

A simple example might be:

Suppose you have a Kaulig function instead of a Nation.

Where Cowlegs (THETA) is not in THETA degrees, but in the number of cows is LL. I expect

And Cowlegs (THETA) gives the number of legs in THETA (ie, the number of LL cows).

Thus, THETA = 1 (ie 1 LLCO), Cowlegs (THETA) = Cowlegs (1) = 4 feet (from 1 LLCO).

Weaver, ume HALFcows also calculated (not LLcows).

The number of legs, CowlegsH nction (THETA) must first be converted to THETA

Suitable drive HALFcows, not LLcows

Everyone already knows this change (ie 2 HALF cows match 1 small cow).

Just like Cowlegs (no sin) and CowlegsH (no sin):

If THETA = 1 LLCO, then Cowlegs (THETA) = sin (1) = 4 feet and,

Because 1 LL = 2 HALFcows (no equation is required here),

If THETA = 2 HALF COW, then CowlegsH (THETA) = CowlegsH (2) = 4 feet.

Yes, Cowlegs (1) = CowlegsH (2) = 4 Inheritance, per THETA and

Depending on what the partner expects from the unit (size).
