What is sin 80?
sin(90 deg) = 0.9848, approx.
Is it true an acute triangle is always equilateral?
No. All equilateral and equiangular triangles are acute. (All angles are equal to 60°, which is less than a right angle [90°]); however, the converse (which is what was asked) is not true.A triangle can have all three angles be less than 90°, but not be an equilateral triangle.An example is a triangle with angles of 80°, 60°, and 40°. It is scalene and acute.From the Law of Sines: a/sin(A) = b/sin(B) = c/sin(C), you can show that sin(80°) does not equal sin(60°) or sin(40°), so none of sides a, b, and c, are equal.You could have an acute isosceles triangle like: 80°, 80° and 20° angles, as another example. From the Law of Sines, you can show that two of the sides are equal, but the third side (opposite the 20° angle) is not equal to either of the other 2.
When was Sin Sin Sin created?
Sin Sin Sin was created on 2006-05-22.
How do you simplify cos times cot plus sin?
cos*cot + sin = cos*cos/sin + sin = cos2/sin + sin = (cos2 + sin2)/sin = 1/sin = cosec
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 makes sin sin?
Sin is typically understood as actions or thoughts that violate moral or ethical standards, particularly those set by religious or legal authorities. It is often seen as harmful to oneself, others, or the natural order, and is considered to be contrary to divine or moral law. Each culture and belief system may have its own specific definitions of what constitutes sin.
How do you simplify cos times cot plus sin?
cos*cot + sin = cos*cos/sin + sin = cos2/sin + sin = (cos2 + sin2)/sin = 1/sin = cosec
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)
Which is smaller sin 0 or sin 200?
i think sin 200 is smaller than sin 0.. because sin 200= - sin 20.. sin 0 = 0 of course 0 > - sin 20
What does hello means in Eastern Visayas Language?
sin sin sin sin
When was Sin After Sin created?
Sin After Sin was created on 1977-04-23.
What is an intention of a sin?
it is thinking over a sin. trying a sin. meaning to sin.
What is cos if csc -9?
Cosec = -9 => sin = -1/9 Then, cos2 = 1 - sin2 = 1 - (-1/9)2 = 1 - 1/81 = 80/81 and so cos = sqrt(80/81) = ±8.94/9 = ±0.99
