Express tan theta in terms of cosec theta
Verify the identity. Show your work. cot2x + csc2x = 2csc2x - 1 1+cosec^2x +cosec^2x Cot^2x+cosec^x= 1+2 cosec^2x Would this be correct?
Q.1 Prove the following identities:- (i) tan^3x/1+tan^2x + cot^3x/1+cot^2 = 1-2sin^x cos^x/sinx cosx (ii) (1+cotx+tanx)(sinx-cosx)/sec^3x-cosec^3x = sin^2xcos^2x.
Prove the following identities: a) (cosec θ + cotθ)(cosecθ - cotθ) = cotθtanθ b) 2/(1 + sinθ) + 1/(1- sinθ) = (3sec^2)θ - tanθcosecθ I basically just have to prove Left
Prove that cosec A_cotA by cosecA+Costa + cosecA+ Cot A by cosecA_cotA=2 cosec squareA_1=2Ã—1+cos squares by1_cos squareA
PROVE THAT (1+COT A+TAN A)(SIN A-COS A)=SEC A\COSEC A-COSEC A\SEC A
Find the exact value of tan(a-b) sin a = 4/5, -3pi/2<a<-pi; tan b = -sqrt2, pi/2<b<pi identity used is: tan(a-b)=(tan a-tan b)/1+tan a tan b simplify answer using radicals. (a is alpha, b is beta)
Find all solutions to the equation tan(theta)+sqrt3=0 Write your answer in terms of pi and us the or button as necessary.
Show that if A, B, and C are the angles of an acute triangle, then tan A + tan B + tan C = tan A tan B tan C. I tried drawing perpendiculars and stuff but it doesn't seem to work? For me, the trig identities don't seem to plug in
If cot¤=7/8,find sin¤, Cos¤,Tan¤,Cosec¤,Tan¤
