If your calculator does not have sin, cos and tan buttons then you have a long task ahead.First, if the angle is measured in degrees, convert it to an angle measured in radians. To do this multiply the angle by pi and divide by 180.
Then
sin(x) = x - x^3/3! + x^5/5! - x^7/7! + ... where k! represents 1*2*3*...*k.
cos(x) = 1 - x^2/2! + x^4/4! - x^6/6! + ...
Keep going until the series converges.
tan(x) is most easily calculated as sin(x)/cos(x).
What else can I help you with?
How do you find sine cosine and tangent of 210 degrees?
Sine = -0.5 Cosine = -0.866 Tangent = 0.577
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 a cotangent?
Cotangent is ' 1/tangent' or ' Cosine / Sine'.
What is cos on a calculator mean?
Cos is short for Cosine ( Complementary Sine) Similrly Sin is short for Sine Tan is short for Tangent.
Do you need a right traingle to use sine cosine and tangent?
Yes, sine, cosine, tangent definitions are based on right triangles
What does tangent on a scientific calculator mean?
It is a trigonometric function, equivalent to the sine of an angle divided by the cosine of the same angle.
How do you find an angle using sine cosine tangent?
First make sure your calculator is in 'Degree Mode (D)'. Then using the 'Inverse' of 'Sin' , shown as 'ArcSin' or ' Sin^(-1)' . enter '0.5', followed by '=' . The answer should be '30' ( 30 degrees).
What is the relationship between the tan and cot?
Cotangent is 1 / tangent. Since tangent is sine / cosine, cotangent is cosine / sine.
What is the reciprocal of a tangent?
Reciprocal of tangent is '1 /tangent' or ' Cosine / Sine '
How do you find theta for right triangle?
You can use your trigonometric functions (sine, cosine, and tangent).
How do you know when to use tangent cosine or sine?
It depends on what information you already have. For example, if you know the length of two sides of a triangle, you can easily find the tangent. Or, if you know the length of two angles and a side, you can find the other sides as well, using the tangent, cosine, and sine as needed.
What dies COS stand for on calculator?
Cos is short for 'Cosine' / It is the complementary curve to 'Sine'.
