Disprove sinx+sin5x=tan3x

Mathematics
1 answer:
Nonamiya [84]4 years ago
5 0
Counter-example:
set x=π/6
LHS=sin(π/6)+sin(5π/6)=1/2+1/2=1
RHS=tan(3π/6)=tan(pi/2)=∞
since LHS≠RHS for the counter-example given, the statement
<span>sinx+sin5x=tan3x
</span>is false.

What is the equation of the line that is perpendicular to 3x -6y =2 and contains the point (-2,--5)​
julsineya [31]

Answer:

y=-2x-12

Step-by-step explanation:

first, putt 3x-6y=2 in standard form:

subtract 3x from both sides: -6y=-3x+2

divide both sides by -6 to isolate y: y=1/2x-1/3

if the other line is perpendicular to this, you must find the slope by finding the opposite reciprocal of 1/2x: -2

now we have 2 points a slope, so we use the point-slope formula: y-y1=m(x-x1)

y+2=-2(x+5)

Use the distributive property: y+2=-2x-10

subtract 2 for both sides to isolate y: y=-2x-12
