How would you establish this identity: (1+sec(beta))/(sec(beta))=(sin^2(beta))/(1-cos(beta)) on the right, sin^2 = 1-cos^2, that factor to 1-cos * `1+cos, then the denominator makes the entire right side 1+cosB which is 1+1/sec which is 1/sec (sec+1)
verify that each of the following is an identity: 1) cos x/ 1-sin^2x= sec x 2) sec x/sin x - sin x/cos x = cot x 3) 1+tan^2ø/ cos ^2ø = sec^4 ø I really need ur help :) thank u so much
for (sec x -1)(sec x + 1) = tan^(2) x so far I got up to: (sin^(2)x / cos x) (-sin^(2)x / cos x) what would the next step be? steps too please
Solve this equation algebraically:(1-sin x)/cos x = cos x/(1+sin x)---I know the answer is an identity, and when graphed, it looks like cot x. I just don't know how to get there. I tried multiplying each side by its conjugate, but I still feel stuck. This is what I have so far:cos^2(x)/cos x + sin x = cos x - sin x/cos^2(x)...but I'm not really sure how to get to the answer. Help please?Thank you!
how would you prove that sin^2(a)-cos^2(b)= sin^2(b)-cos^2(a).i'm not completely sure that this is right but i used the difference of two squares on it to get (sin(a)+cos(b))(sin(a)-cos(b)) then after that i am stuck. please help
how would you create an equation for sec(2x) using both sec(x) and csc(x)?the steps i have so far are 1/(cos^2(x)-sin^2(x))= 1/(1-1)/(sec^2(x)-csc^2(x))but then i do not know what to do after this.
Prove this identity(cos è - 1) / (cos^2 è) = sec è - sec^2 èI have a question when you simplify the secant in terms of cosine. Would you cross multiply but then again there's the subtraction sign there instead of a multiplication sign? then would you multiply by the lcd to get the demoniator to be the same for both sides, im really confused, please help me, thanks
Prove that Sin(theta)times Cos(theta) divided by Cos^2(theta)-Sin^2(theta)=Tan(theta) divided by 1-Tan(theta) Show step by step how to change the left to equal the right side of equasion
Yesterday I learned to solve a right triangle assuming I know the 3 angles and 1 side. I can now establish the lengths of the 2 other sides using a sine table I printed off the net. Today I hope I will learn to solve a right triangle but now I only know 1 angle (the right angle) and 2 sides (not the hypotenuse). How do I establish the other 2 angles? Help please. Thank you, Mike.You know two sides,...
Find the components of the unit vector that makes an angle of 210 degrees counterclockwise with the positive x-axis(-√3/2,-1/2) which would be the same as (cos 210º,sin 210º)
Please help me simplify the following: 4sin2x*cos2x 1-sec^2*x cos^2*x-sin^2*x Thank you
