Basic understanding of the trigonometric equation problemsin2p=2cos2pis to simplify the equation by using the trigonometric formulasin2p=2sinpcosp. After that factorization of the equation was performed easily. Both obtained factors of the equation are equated...
Given the equation sin 2x=2sin x.Is the equation an identity or a conditional equation? Explain. 相关知识点: 试题来源: 解析 The equation is a conditional equation. Because left side is not equal right side after solving. It is rue only when there is condition like x=0 or x=π . ...
Using only trigonometric functions, solve for phi. 1. a) Verify that x=A cos (\omega t+\phi )+Bsin(\omega t+\phi) (for A and B arbitrary constants) is a solution to the differential equation: \ddot{x}=-\omega ^{2}x b) Show that this solution can be rewritten as x=C cos(...
To solve the equations cotx=2 and sin2x=1, we will follow a systematic approach. Step 1: Solve cotx=2 The cotangent function is defined as:cotx=cosxsinxSetting this equal to 2 gives:cosxsinx=2This can be rearranged to:cosx=2sinx Step 2: Solve sin2x=1 The double angle formula for si...
Select several values of x (for example, x=0, x=π( 2), x=π) and calculate both the left and right sides of the equation (1).Let x=0.Left side: sin 2x=sin 0=0Right side: (split)2sin x&=2sin 0\&=2* 0\&=0(split)Let x=π2Left side: (split)sin 2x&=sin (2⋅ ...
When we are looking for values of the unknowns that satisfy a set of equations, then we call this set a system of equations, and the numbers in question, solutions of the system. For example, the equationsx+ 2y= 5, 2x+y – z= 1 are a system or two equations in three unknowns....
