Write 3 equivalent expressions for cotax + 1. (3) 2. Write the following in terms of sin x only (2x2) a) tan x + 1 b) cosx 3. Prove that f(x) = sin(x) is an oddFor the best answers, search on this site https://shorturl.im/avtCZ. Hi, sin2x + sinx = 0 2sinxcosx + sinx = 0 sinx(2cosx + 1) = 0 sinx = 0 ==> x = 0° and x = 180° 2cosx + 1 = 0 ==> cosx = -1/2 ==> x = 120° and x = 240°Know how to solve basic trig equations. There are 4 types of basic trig equations: sin x = a ; cos x = a; tan x = a ; cot x = a; Solving basic trig equations proceeds by studying the various positions of the arc x on the trig circle, and by using trig conversion table (or calculator).Sinθ = $\frac{{\rm{p}}}{{\rm{h}}}$ cosθ = $\frac{{\rm{b}}}{{\rm{h}}}$ tanθ = $\frac{{\rm{P}}}{{\rm{b}}}$ cotθ = $\frac{{\rm{b}}}{{\rm{P}}}$ secθ = $\frac{{\rm{hYou can put this solution on YOUR website! sin(2x) = sin(x) Using the identity sin(2x) = 2sin(x)cos(x) this becomes: 2sin(x)cos(x) = sin(x) Subtracting sin(x) from each side: 2sin(x)cos(x) - sin(x) = 0

sinx - sin2x = 0 Solve X? | Yahoo Answers

Free trigonometric equation calculator - solve trigonometric equations step-by-stepBest Answer. sin2x - cosx = 0 . 2sinx cos x - cosx = 0 factor out cosx . cosx [ 2sinx - 1] = 0 set each factor to 0 . cosx = 0 and this happens at 180°sin2x-sinx=0. Let's use an identity for sin(2x).....this = 2 sinxcosx. So we have. 2sinxcosx - sinx = 0.....let's factor out the sin x....so we have. sinx (2cosx -1) = 0. Setting each factor to 0, we have. sinx = 0 and 2cosx -1 =0. Solving the first, we have x = 0 + (pi)n. Solving the second, we have. cosx = 1/2. so x = (-pi/6) + 2(pi)n. and xGiải phương trình: sinx + cosx + 1 + sin2x + cos2x = 0 .

2sinx/sin2x is equivalent to what can someone please explain the following steps and answer to complete this question thanks!!Question: 7. Solve: Sin2x + Sinx = 0 For The Interval [0,2A) 7. This problem has been solved! See the answer. Show transcribed image text. Expert AnswerGet an answer for '`tan(2x) - 2cos(x) = 0` Find the exact solutions of the equation in the interval [0, 2pi).' and find homework help for other Math questions at eNotesSolve the trig equation, involves using a double angle formula and factoring.Need more help? Mr. Dwyer is available for 1-on-1 tutoring online. Details at ht...sinx (2cosx - 1) =0. Now 2 things multiplied together are 0 one or both is 0. i.e. a*b =0 implies a or b is 0. In the above therefore either sinx =0 which implies x is 0 or 2cosx -1 =0
