As the second equation may be expressed as #sin (x)/cos (x)=1/2#, violating our initial condition of #tan (x)!=1/2#, we will only focus on the first.

Mar 4, 2018 · Use sin difference identity sin (4x) sin (theta-alpha)= sintheta*cosalpha-costheta*sinalpha So in this case sin (5x-x)= sin5x*cosx-cos5x*sinx sin (4x)

Use a calculator or use the "SOH CAH TOA" rule. In trigonometry, Given a Triangle, Sine = ("Opposite")/ ("Hypotenuse") Cosine = ("Adjacent")/ ("Hypotenuse") Tangent ...

Oct 8, 2017 · 3/5. We have, from the Right- DeltaABP, AB^2+BP^2=AP^2. :. AP^2= (2y)^2+y^2=5y^2. Similarly, AQ^2=5y^2, and, PQ^2=2y^2. Applying the Cosine-Rule in …

(1-tan (x/2))/ (1+tan (x/2))=secx-tanx and not secx Multipying numrator and denominator of (1-tan (x/2))/ (1+tan (x/2)) by cos (x/2), we get (1-tan (x/2))/ (1+tan (x ...

Feb 18, 2018 · Verify these identities? sin^2x-tan^2x = -sin^2xtan^2x 1/ (secx-tanx) = tanx+secx

Explanation: As #arcsin (sina)=a#, #arctan (tanb)=b# and #arccos (cosc)=c#
