Prove that (1-tan (x 2)) (1+tan (x 2))=secx? | Socratic
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 2) = cos(x 2) − sin(x 2) cos(x 2) + sin(x 2) = cos(x 2
How would you prove the following equation? (secx) (1-tanx . . . - Socratic
How would you prove the following equation? # (secx) (1-tanx) = (1) (cosx-sinx)# Thank y'all for the help!
How do you find the derivative of [secx (tanx - Socratic
How do you find the derivative of [sec x(tan x + cos x)]?
Find the derivative of #1 (secx-tanx)#? - Socratic
Explanation: As #sec^2x=tan^2x+1#, we have #sec^2x-tan^2x=1# i e # (secx+tanx) (secx-tanx)=1# and #1 (secx-tanx)=secx+tanx# Hence #d (dx) (1 (secx-tanx))=d (dx) (secx+tanx)# = #secxtanx+sec^2x# Answer link You can reuse this answer
Verify these identities? sin^2x-tan^2x = -sin^2xtan^2x 1 (secx-tanx . . .
#sin^2x-tan^2x=sin^2x (1-1-tan^2x)=-sin^2xtan^2x#
Can anyone help me differentiate this function? y=sec x 1+ sec x
Explanation: #y= secx {1+sec x} = 1 {1+cos x}# So #dy dx = -1 (1+cosx)^2 times (-sin x) = sin x (1+cos x)^2# Answer link Douglas K Feb 26, 2018 Given: #y = sec
