Find all solutions. Where k is the integer. please show steps! thank you
Solve for ALL values of x in the real number system. If an EXACT solution does not exist, round your answers to the nearest hundredth. sin2x = sinx
Solve for x in the interval... 0<x<2π: 3sin2(2x+1)+2sin(2x+1)-1=0 My teacher says there should be 6 answers. I have a TI-84 calculator, so maybe...
One end of a 9.3 foot pole is 13.6 feet from an observer's eyes, and the other end is 17.4 feet from the observer's eyes. Through what angle does the observer see the pole?
My professor said for this problem to use inverse trig functions, half angle, and double angle identities. Evaluate: tan(2sin-1(4/5)) Please list the answer...
Convert the following from Polar to Rectangular Form: r=3sinΘ(Theta)-4cosΘ(Theta)
Prove: 1-cos2x/1+cos2x=tan2x Please include step by step and next to each step, please include the identity used! :)
Prove: sinx/sinx+cosx)=tanx/1+tanx If you could, please list the steps and include the identities next to the steps.
Prove: SQUARE ROOT OF (3cosx+4sinx)2+(4cosx-3sinx)2 = 5 Please include step by step and the identities used next to each step! :)
Prove: (secx+tanx)^3(secx-tanx)^4=1-sinx/cosx Please show the steps and prove this by making both sides equivalent to each other. Also, please include which identities follow...
Using the pythagorean identity, find the value of sin⊗ and tan⊗ if cos⊗= -1/2
Explain why sin⊗2 + cos⊗2=1
Give an explanation.
A.0 B.2 C.1 D.Infinity I need a step by step on how to do this.
2sin2θ=sinθ
If 0<x<1, write cos(sin-1 x) as an algebraic expression in x.
How do I prove that sin^2 x(1 + cot^2 x) = 1 thanks
This is for my trig class, thanks for the help!
