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{h
How about the following: Start with: sin(x) = cos(x) Divide both sides by cos(x) to get: sin(x)/cos(x) = cos(x)/cos(x) Recognize that sin(x)/cos(x) is tan(x) Recognize that cos(x)/cos(x) is unity So we have: sin(x)/cos(x) = tan(x) = 1 so x

sin2x - sinx = 0 . 2sinxcosx - sinx = 0. x. 2sin. 1. 2 x. 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. ∫ π/4. 0 tan(x)dx. sinx =-1 + 2πn. Step-by-step explanation: sin2x + sin x
im just having trouble figuring out how it went from the original equation to sin(x) 2sin(x)-1=0? Jose,. sin2(x) is sin(x) × sin(x) so 2sin²

Solve sin3x+sin2x-sinx=0 - Math - Trigonometric Functions. Derivering ger att f (x) = −4 sin x + 4 sin(2x) = 0. Genom att använda formeln för dubbla vinkeln av sinus så får vi. −4 sin x + 8 sin x cos x = 0,. sin 2x - sin x = 0. Men hjälper det mig något? En annan lösning jag har sett är: 2sinxcosx - sinx = 0 sinx(2cosx - 1) = 0. En annan lösning jag har sett är: 2sinxcosx - sinx = 0 sinx(2cosx - 1) = 0. Men där förstår jag inte
lim x→0 sin 2x x. = A. 0. B. 1. C. 2. D. 1/2. E. Inget av ovanstående x > 0 sinx + cosx, x ≤ 0.Men hjälper det mig något?

解，因为cos2x+cosx=0，cos2x=2（cosx）^2-1 所以2（cosx）^2+cosx-1=0 所以cosx=-1或cosx=1 所以sin2x+sinx=0或sin2x+sinx=∨3或sin2x+sinx=-∨3
