The concept of sine was invented by an Indian mathematician "Aryabhatta". Aryabhatta discussed the concept of sine in his work by the name of ardha-jya. Literally, it means "half-chord". For simplicity, people started calling it jya. When Arabic writers translated his works from Sanskrit into Arabic, they referred it as jiba. However, in Arabic writings, vowels are omitted, and it was abbreviated as jb. Later writers substituted it with jiab, meaning "cove" or "bay." (In Arabic, jiba is a meaningless word.) Later in the 12th century, when Gherado of Cremona translated these writings from Arabic into Latin, he replaced the Arabic jiab with its Latin counterpart, sinus, which means "cove" or "bay". And after that, the sinus became sine in English

Which angle has a negative sine and a positive cosine?
All the angles in 4th quadrant have positive cosine and negative sine e.g. 280,290,300,310...etc.
Is 35 degrees cos or sin?
Every angle has a sine and a cosine. The sine of 35 degrees is 0.57358 (rounded) The cosine of 35 degrees is 0.81915 (rounded)
What is the tangent if the sine is three fifths?
If the sine is 3/5, the tangent must be 3/4, and the triangle must be a 3-4-5 Pythagorean triangle.
How do you find the sin of a triangle?
Sin is opposite over hypotenuse. Just think of this to help you: SOH-CAH-TOA Sine = opposite over hypotenuse Cosine = adjacent over hypotenuse Tangent = opposite over adjacent Hope that helps you.
How do you solve 5SecX plus 3CosecX equals 0 with a Range 0 To 360 Degrees?
Well, let's see.secant = 1/cosinecosecant = 1/sine5/cosine + 3/sine = 0Multiply both sides of the equation by sine :5 sin/cos + 3 = 0But sin/cos = tangent .5 tan(x) + 3 = 05 tan(x) = -3tan(x) = -0.6'x' is the angle whose tangent is -0.6 .
How does the tangent function relate to sine and cosine?
Tangent = sine/cosine provided that cosine is non-zero. When cosine is 0, then tangent is undefined.
How do you find sine cosine and tangent of 210 degrees?
Sine = -0.5 Cosine = -0.866 Tangent = 0.577
Do you need a right traingle to use sine cosine and tangent?
Yes, sine, cosine, tangent definitions are based on right triangles
What is the relationship between the tan and cot?
Cotangent is 1 / tangent. Since tangent is sine / cosine, cotangent is cosine / sine.
The laws of sine cosine and tangent are used where?
in trigonometry
Does tangent of x equal cosine divided by sine?
No, it does not.
What jobs use sine cosine and tangent?
Trigonometry
The tangent of an angle equals the ratio of the?
Sine of the angle to its cosine.
What is Secant - cosine equals sine tangent?
It is a FALSE statement.
Which ratio describes the tangent function?
The ratio of sine and cosine.
Why does the world have cosine sine tangent?
For solving the properties of triangles
How do you find an angle using sine cosine tangent?
If you know the angle's sine, cosine, or tangent, enter it into the calculator and press <inverse> sine, cosine, or tangent. On MS Calc, in Scientific Mode, using Degrees, enter 0.5, then check Inv and the press sin. You should get 30 degrees. The other functions work similarly.
