How many solutions does sin x have?
I get an answer of 0 on my calculator, but in reality, sin x = 0 has an infinite number of solutions. As you can see on the graph, I get 0 for sin x every 2pi spaces.
How do you know how many real solutions a system has?
A system of two equations can be classified as follows: If the slopes are the same but the y-intercepts are different, the system has no solution. If the slopes are different, the system has one solution. If the slopes are the same and the y-intercepts are the same, the system has infinitely many solutions.
How many solutions are there to the system?
A system of linear equations usually has a single solution, but sometimes it can have no solution (parallel lines) or infinite solutions (same line).
How many solutions does X X have?
Sample Problems The equation x = x has infinitely many solutions: any value of x will work, since x is always equal to itself. The equation y2 = -5 has no real number solutions because the square of any real number is positive.
How many solutions does sin x )= 3 have?
Trigonometry Examples The range of sine is −1≤y≤1 – 1 ≤ y ≤ 1 . Since 3 does not fall in this range, there is no solution.
How many solutions does this linear system have y 2x 5?
one solution
The linear system y = 2x – 5 and -8x – 4y = -20 has only one solution.
How many solutions does this equation have 6h − 9 − 3h )= 6 − 3 H 2?
This equation has no solution.
How many solutions does X X 5 have?
Sample Problems The equation x = 5 has only one solution: the number 5.
How many solutions does sin x )= 1 3 have?
infinite solutions
Considering the function y = sin(x) for a given value of y, like y = -1/3, there are infinite solutions of x, as y is equal to -1/3 at multiple points along the function.
How to find the number of solutions in a system of equations?
Number of Solutions in a System of Equations. A linear equation in two variables is an equation of the form ax + by + c = 0 where a, b, c ∈ R, a, and b ≠ 0. When we consider a system of linear equations, we can find the number of solutions by comparing the coefficients of the equations. Also, we can find the number of solutions by graphical method.
How do you find the number of solutions to a graph?
If we plot the graph, the lines will intersect. This type of equation is called a consistent pair of linear equations. 2. If (a 1 /a 2) = (b 1 /b 2) = (c 1 /c 2 ), then there will be infinitely many solutions. The lines will coincide.
How many solutions does (a 1/a 2) = (B1/B2)?
If (a 1 /a 2) = (b 1 /b 2) = (c 1 /c 2 ), then there will be infinitely many solutions. This type of equation is called a dependent pair of linear equations in two variables. If we plot the graph of this equation, the lines will coincide. Case 2. If (a 1 /a 2) = (b 1 /b 2) ≠ (c 1 /c 2 ), then there will be no solution.
