What is the vaule of trigonometric functions cos 270?
cos(270) = 0
How do you know which trigonometric ratio to use when finding the measure of an angle?
Sin= Opposite leg/Hypotenuse Cos= Adjacent leg/ Hypotenuse Tan=Adjacent leg/ Opposite leg
Express all the trigonometric ratios of cosA?
sin = sqrt(1 - cos^2)tan = sqrt(1 - cos^2)/cossec = 1/coscosec = 1/sqrt(1 - cos^2)cot = cos/sqrt(1 - cos^2)
Why in dot product you use cos and in vector product sin?
We use the dot product cos and in vector we use the vector product sin because of the trigonometric triangle.
How do you prove this trigonometric relationship sin3A equals 3sinA cos 2 A - sin 3 A?
sin(3A) = sin(2A + A) = sin(2A)*cos(A) + cos(2A)*sin(A)= sin(A+A)*cos(A) + cos(A+A)*sin(A) = 2*sin(A)*cos(A)*cos(A) + {cos^2(A) - sin^2(A)}*sin(A) = 2*sin(A)*cos^2(A) + sin(a)*cos^2(A) - sin^3(A) = 3*sin(A)*cos^2(A) - sin^3(A)
What is cos 22?
cos(22) is a trigonometric ratio and, if the angle is measured in degrees, its value is 0.9272
What is cos(22 degrees)?
cos(22) is a trigonometric ratio and, if the angle is measured in degrees, its value is 0.9272
What is the vaule of trigonometric functions cos 270?
cos(270) = 0
How do you know which trigonometric ratio to use when finding the measure of an angle?
Sin= Opposite leg/Hypotenuse Cos= Adjacent leg/ Hypotenuse Tan=Adjacent leg/ Opposite leg
What the three main trigonometric ratios mean?
sin, cos and tan
What is the correct trigonometric ratio is for tan?
For a right angle triangle the trigonometrical ration is: tangent = opposite/adjacent
What is cos(22) in physics?
In physics, cosine function is used to determine the x-component of a vector. So cos(22) in physics would give you the x-component of a vector that makes an angle of 22 degrees with the positive x-axis.
The trigonometric ratio cosine is equal to?
opposite over adjacent
Express all the trigonometric ratios of cosA?
sin = sqrt(1 - cos^2)tan = sqrt(1 - cos^2)/cossec = 1/coscosec = 1/sqrt(1 - cos^2)cot = cos/sqrt(1 - cos^2)
What dies COS stand for on calculator?
"COS" stands for "Cosine", which is one of the 6 trigonometric functions. Similarly, "SIN" stands for Sine, and TAN stands for Tangent.
Use trigonometric identities to write each expression in terms of a single trigonometric function or a constant. simplify cos t sin t?
Thanks to the pre-existing addition and subtraction theorums, we can establish the identity:sin(a+b) = sin(a)cos(b)+sin(a)cos(b)Then, solving this, we getsin(a+b) = 2(sin(a)cos(b))sin(a)cos(b) = sin(a+b)/2a=b, sosin(a)cos(a) = sin(a+a)/2sin(a)cos(a) = sin(2a)/2Therefore, the answer is sin(2a)/2.
Why in dot product you use cos and in vector product sin?
We use the dot product cos and in vector we use the vector product sin because of the trigonometric triangle.
