What is sine of 45 degrees?
one over root of 2 or (1/square root of 2) or 1/1.414213562 or 0.707106781
What is sin cos tan csc sec cot of 30 45 60 degrees?
Sin(30) = 1/2 Sin(45) = root(2)/2 Sin(60) = root(3)/2 Cos(30) = root(3)/2 Cos(45) = root(2)/2 Cos(60) = 1/2 Tan(30) = root(3)/3 Tan(45) = 1 Tan(60) = root(3) Csc(30) = 2 Csc(45) = root(2) Csc(60) = 2root(3)/3 Sec(30) = 2root(3)/3 Sec(45) = root(2) Sec(60) = 2 Cot(30) = root(3) Cot(45) = 1 Cot(60) = root(3)/3
What is the tan of 120 in fraction form?
Tan(120) = Sin(120) / Cos(120) = [sqrt(3)/ 2 ] / [ -1/2] [sqrt(3)/ 2 ] / [ -1/2] Division of fractions. [sqrt(3) / 2 ] X [ -2/1] Cancel down by '2' sqrt(3) / -1 = sqrt(3 = -1.732050808.....
If sinX plus cosecx equals 2 find sin40x plus cosec50x?
sin x + csc x = 2 sin x + 1/sin x = 2 (sin2 x + 1)/sin x = 2/1 (cross multiply) sin2 x + 1 = 2sin x (subtract 2sin x to both sides) sin2 x - 2sinx + 1 = 0 (sin x - 1)2 = 0 (take the square root of both sides) sin x - 1 = 0 (add 1 to both sides) sin x = 1 x = sin-1 1 = 90⁰ 40x = 40(90⁰) = 3,600⁰ sin 40x = sin (3,600⁰ ) = 0 50x = 50(90⁰) = 4500⁰ sin 50x = sin (4,500⁰) = 0, so that csc 50x is undefined, we cannot divide by 0. Then, sin40x + csc50x is undefined.
If cos and theta 0.65 what is the value of sin and theta?
Remember use the Pythagorean Trig/ Identity. Sin^(2)(Theta) + Cos^(2)(Theta) = 1 Algebraically rearrange Sin^(2)(Theta) = 1 - Cos^(2)(Theta) Substitute Sin^(2)(Theta) = 1 - 0.65^(2) Factor Sin^(2)(Theta) = ( 1- 0.65 )( 1 + 0.65) Sin^(2)(Theta) = (0.35)(1.65) Sin^(2)(Theta) = 0.5775 Sin(Theta) = sqrt(0.5775) Sin(Theta) = 0.759934207.... Theta = Sun^(-1)(0.759934207...) Theta = 49.45839813 degrees.
What is sin 45?
one over the square root of 2 or 0.850903525
Solve sin x square root of 3 divided by 2?
1.5
Are they equal sin-30equals -sin30?
sin-30 = (-1) x 1/(square root of 2) -sin30 = -(1/square root of 2) They are equal
How do you solve 2 sin squared x?
Do sin(x), square it, and then multiply it by two.
How do you differentiate cosine square root of x?
The derivative of cos x is -sin x, the derivative of square root of x is 1/(2 root(x)). Applying the chain rule, the derivative of cos root(x) is -sin x times 1/(2 root(x)), or - sin x / (2 root x).

36
What is the exact value of sin 405?
sin(405) = square root of 2 divided by 2 which is about 0.7071067812
What is sin 60 degrees?
square root 3/2
What is sin 45 degrees?
1/square root 2
What is the sin of 1305 degrees?
sin(1,305) = sin(225) = -0.70711 (rounded) = 1/2 of the negative square root of 2.
Solve square root 4 to the 2 power?
PLUS 2
What is the derivative of square root 2 sin x?
It is not totally clear to what the square root applies*; if just the 2, then: d/dx ((√2)sin x) = (√2) cos x if all of 2 sin x, then: d/dx (√(2 sin x)) = cos x / √(2 sin x) * for the second version I would expect "square root all of 2 sin x" but some people would write as given in the question meaning this, so I've given both just in case.
