Solve for : ſJx+ Vp + √5x - √p = √2/x+2/a Ip+9 2P. Verify the following identities: sin (-e) cos(@) b) cos(-e)- sin() Use in(A-B)sinAcosB -SinBcosA cosA-B) = cosAcosB + sinAsinB

Answer 1

1 x + JP + 55-Jp = 125x+251 - Sorvaring both the sides we have • (5x + 1/2) + (50 - $) + 250-16 = 25x + 250 251 +25x6 =24 + 250 SX-P = For on savaring both the sides we get x-p=q x=p+w] An P.LHS = sin(&-0) - Sin caso - cos sin D = 1xcond - Oxsing = caso - RHS DEP. LHS - COS(E-2) = Cascs 0 + Son şi sin 8 = oxcond + 1 xsil = sind - RHS QEN.
