Inverse sine is one of the inverse trigonometric functions of the sine function and it is written as sin-1x and is read as "sin inverse x". Then by the definition of inverse sine, θ = sin-1[ (opposite side) / (hypotenuse) ]
Step 6: Use the sine addition formulaRecognizing that 1√2=sin(π4), we can express the argument of the sine inverse as: LHS=sin−1(sin(π4+θ2)). Step 7: Apply the sine inverse propertySince the sine function is one-to-one in the range (−π2,π2): LHS=π4+θ2. Step...
Using the sine addition formula sin(t+a)=sintcosa+costsina, we can substitute:I=∫sintcosa+costsinasintdtThis simplifies to:I=∫(cosa+costsinasint)dt Step 4: Separate the IntegralWe can separate the integral:I=∫cosadt+∫costsinasintdtThe first integral is straightforward:∫cosadt=cosa⋅...
Sin Double Angle Formula The sine double angle formula is {eq}\sin 2\theta = 2\sin\theta \cos\theta {/eq}. This comes from the angle addition formula. Remember, {eq}\sin (x+y) = \sin x\cos y + \sin y \cos x {/eq}. Then, because {eq}2\theta = \theta + \theta {/eq...
