· How do you prove #\csc \theta \times \tan \theta = \sec \theta#? · cosecant of angle θ = cosecθ = Hypotenuse Perpendicular secant of angle θ = secθ = Hypotenuse Base Note that, sine, cosine, tangent, cotangent, cosecant, and secant are called Trigonometric Functions that defines the relationship between the sides and angles of the triangleCosine squared plus sine squared equals 1 can also be written cosine squared theta equals 1 minus sine squared theta or sine squared theta equals 1 minus cosine squared theta Now the original cosine double angle formula is this, cosine of 2 theta equals cosine squared theta minus sine squared theta, but I can use my Pythagorean identities to rewrite this, so another form
I hope this video helpful to you, if Yes!So, in either case, the result can never be equal to 2 The final result would be ,sin^2 (theta)cos^2 (theta)=1–2cos^2 (theta) and this is also a well known and widely used trigonometric identity After squaring both terms will become positive , so we are subtracting a positive number by aSolution 2Show Solution ⇒ ` (1 sin θ)^2/cos^2 θ = P^2`, (Squaring both sides) ⇒ ` (1 sin^2 θ 2 sin θ cos^2 θ)/ (1 sin^2 θ 2 sin θ cos^2 θ) = (p^2 1)/ (p^2 1)` (Applying componendo and dividendo ⇒ ` (1 1 2 sin θ)/ (sin^2 θ sin^2 θ 2 sin θ) = (p^2 1)/ (p^2 1)` Hence proved
