I thought it could possible be solved by a double angle formula, but I cant seem to make it work
I thought it could possible be solved by a double angle formula, but I cant seem to make it work
NO OTHER ADDITIONAL DETAILS
I have no idea what half of the words are in this problem, much less how to solve it. I'm not sure what equation(s) I would use to work it as well. If it's any hint we're working on trigonometric...
could u prove this please
can u please help me to prove this rhs=lhs
I'm stumped on this one! help please!
ln|1+cos(theta)|+ln|1-cos(theta)| = 2ln|sin(theta)|
Sin(A-B) / (SinASinB) = CotB - CotA
How do I find the polar coordinates of the points on the polar curve r=cos(theta)+sin(theta), 0(greater than or equal to)(theta)(less than or equal to)(pi), where the tangent line is horizontal...
csc / (1 + csc) = (1 - sin) / cos^2
True or False and explain: there is at least one point x between 0 and π/2 where cos(x)+sin(x)=x^2. Should I try plugging in the two numbers given into the equation or do I need...
cos(x).cos(2x)cos(4x)cos(8x)= sin16x/16sinx prove this !
If 270º <x< 360º , show that √(2+√(2+2cosx)) = 2 sin x/4. Thank You! :)
Prove that cos6x + sin6x = (5+3cos4x)/8 Thank You! :)
Prove that tanx = cotx - 2 cot 2x. Hence show that 2tan20º + 4tan40º + 8tan80º = 9(cot 10º-tan10º) Thank You!:)
can you draw a diagram and explain trigonometry identities for shifts of pi/2, pi, 2pi?
no calc just trig identities please show work! thakns so much for any help!
Prove that (Cos 5/2 A + Cos 3/2 A) / (Sin 3?2A + Sin A/2) ≡ Cot A Cos A - Sin A
Prove Tan (P+Q) - Tan P ≡ Sin Q / Cos P Cos (P+Q)
(Sin x Tan x) / (Tan x - Sin x) ≡ (Tan x + Sin x) / (Sin x Tan x) LHS, (Sin x Tan x) / (Tan x - Sin x)
