Cos θ = 1/sec θ or sec θ = 1/cos θ; Web the reciprocal trigonometric identities are: Sin(x)cot(x) = cos(x) sin ( x) cot ( x) = cos ( x) is an identity = 1 4 ∫sin(2x) u du (2)dx = 1 4 ∫sin(u)du = − 1 4 cos(u) + c = − 1 4cos(2x) + c. Often, if the argument is simple enough, the function value will be written without parentheses, as sin θ rather than as sin(θ). (sin(x)+cos(x))2 = 1+ 2sin(x)cos(x) ( sin ( x) + cos ( x)) 2 = 1 + 2 sin ( x) cos ( x) is an identity. Cot (theta) = 1/ tan (theta) = b / a. ( math | trig | identities) sin (theta) = a / c. Sec (theta) = 1 / cos (theta) = c / b. Csc (theta) = 1 / sin (theta) = c / a.
Thus, sin(x)cos(x) = sin(2x) 2. You can also show that this is equivalent to the other two answers using the identity cos(2x) = cos2(x) − sin2(x). Cot (theta) = 1/ tan (theta) = b / a. Tan θ = 1/cot θ or cot θ = 1/tan θ; From here, let u = 2x so that du = 2dx. Web we will use the identity sin(2x) = 2sin(x)cos(x). ( math | trig | identities) sin (theta) = a / c. Often, if the argument is simple enough, the function value will be written without parentheses, as sin θ rather than as sin(θ). Cos θ = 1/sec θ or sec θ = 1/cos θ; = 1 4 ∫sin(2x) u du (2)dx = 1 4 ∫sin(u)du = − 1 4 cos(u) + c = − 1 4cos(2x) + c. Csc (theta) = 1 / sin (theta) = c / a.
