What else can I help you with?
How do you write ratios for sin and cosine?
sin = opp/hyp cos = adj/hyp tan = opp/adj
What are inverse sine inverse cosine and inverse tangent used for?
to find the measure of an angle. EX: if sin A = 0.1234, then inv sin (0.1234) will give you the measure of angle A
What are the sum and difference identities for the sine cosine and tangent functions?
Sine sum identity: sin (x + y) = (sin x)(cos y) + (cos x)(sin y)Sine difference identity: sin (x - y) = (sin x)(cos y) - (cos x)(sin y)Cosine sum identity: cos (x + y) = (cos x)(cos y) - (sin x)(sin y)Cosine difference identity: cos (x - y) = (cos x)(cos y) + (sin x)(sin y)Tangent sum identity: tan (x + y) = [(tan x) + (tan y)]/[1 - (tan x)(tan y)]Tangent difference identity: tan (x - y) = [(tan x) - (tan y)]/[1 + (tan x)(tan y)]
What dies COS stand for on calculator?
Cos is short for 'Cosine' / It is the complementary curve to 'Sine'.
What is cosine cubed?
It is cosine*cosine*cosine.
What are the units of sin cosine and tangent?
All three are ratios which do not have units.
How do you write ratios for sin and cosine?
sin = opp/hyp cos = adj/hyp tan = opp/adj
How does one differentiate between the sine rule and the cosine rule?
The sine rule is a comparison of ratios: (sin A)/a = (sin B)/b = (sin C)/c. The cosine rule looks similar to the theorem of Pythagoras: c2 = a2 + b2 - 2ab cos C.
Does cosine equal 1-sin?
No, it does not.
Which ratios correctly describes the cosine function?
The cosine function on a right triangle is Adjacent leg divided by the hypotenuse of the triangle.
What trigonometric ratios cannot be greater than one?
Sine and cosine.
What are the basic trigonometric ratios?
Sine(Sin) Cosine(Cos) Tangent(Tan) ---- -Sin of angle A=opposite leg of angle A / hypotenuse -Cos of angle A= Adjacent leg of angle A / Hypotenuse -Tan of angle A= opposite leg of angle A / Adjacent lef of angle A
What is the Derivative of sin?
Generally, the derivative of sine is cosine.
Sin and cosine values of 0?
sin 0 = 0 cos 0 = 1
What is Sin cosine and tangent?
Sin, cosine, and tangent are considered the three main of trigonometry, commonly written as sin, cos, and tan. sin(θ) = O/H cos(θ) = A/H tan(θ) = O/A Where O is opposite Where H is Hypotenuse Where A is Adjacent To assist further in understanding: http://www.mathsisfun.com/sine-cosine-tangent.html
What is the integral of cosine cubed?
The integral of cosine cubed is sinx- 1/3 sin cubed x + c
What are trigometric ratios?
The ratios pertaining to right angled triangles are called trigonometrical ratios.They are- sine x = Opposite side/Hypotenuse cosine x= Adjacent side/Hypotenuse tangent x= Opposite side/Adjacent side Cosecant x= Hypotenuse/Opposite side secant x= Hypotenuse/Adjacent side cotangent x= Adjacent side/Opposite side Here, x is one of the angles in the trangle except the right-angled one.
