WebbIn trigonometry, reciprocal identities are sometimes called inverse identities. Reciprocal identities are inverse sine, cosine, and tangent functions written as “arc” prefixes such as arcsine, arccosine, and arctan. For instance, functions like sin^-1 (x) and cos^-1 (x) are inverse identities. Either notation is correct and acceptable. Webb19 apr. 2024 · We have to simplify sec (θ) sin (θ) cot (θ) Now first of all let's simplify these separately , using reciprocal identities. Sec (θ) = 1/cos (θ) Sin (θ) is already simplified Cot (θ)= cos (θ) / sin (θ) , Let's plug these values in the expression sec (θ) sin (θ) cot (θ) = ( 1/cos (θ) ) * ( sin (θ) ) * ( cos (θ) / sin (θ) ) rob gilmore photography
