How do you figure this out Sin theta equals 0.0138 so theta equals what?
theta = arcsin(0.0138) is the principal value.
When was Sin Sin Sin created?
Sin Sin Sin was created on 2006-05-22.
How do you find perimeter of triangle when two sides are not given?
You have to figure out the two sides. You must have the angles of the triangle and use the sin, cos, and tan functions to figure out the sides. Remember "Oscar Had a Hint of Apples?' sin (x) = o/h cos (x) = a/h tan (x) = o/a So, if the hypotenuse is the only side known, multiply the sin of the angle of the opposite side by the hypotenuse. This gives you the opposite side. Then you can divide the tangent of the angle by the opposite side to get the adjacent side.
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)
