# How can I solve the maths equations quickly

These calculations may help you to solve big calculations. Following are the most used equations which help you to solve any big mathematical equations.

1. :
x = , =
2. :
x = , n = , =
3. :
x = , n = , =
4. :
x = , =
5. :
n = , =
6. : Returns the logarithm of x base y, Note: when x = 10n sometimes output will be the number with .99999999, please round it upwards to the nearest integer. Example: 1000 = 103, when x = 1000, y = 10 output will be 2.9999999999999996 due to floating-point rounding = 3
y = , x = , =
7. How can we find the antilog base 10 of 3 ? It is just a example. 1000 = 103 , Therefore log101000 = 3.  Therefore, Antilog base 10 of 3 is equal to 103. antilog10(x) = ? or :
x = , =
8. Same as the above in 7, we can calculate antiloge(x) = ? or :
x = , =
9. a = , b = , c = , :
x = or x =
10. ax+by+c = 0       and
lx+my+n = 0       then x=?, y=?
a = , b = , c = ,
l = , m = , n = , :
x = and y =
11. Convert degrees to radians, Input valuer of θ in degrees. θ = degrees, = radians
12. Convert (degrees, minutes, seconds) to radians, Input value for θ.
θ = degrees, minuites, seconds
Answer = radians
13. Convert radians to degrees, Input value of x in radians. x = radians, = degrees
14. sin(θ) = ? or sine(θ) = ?, Input the value of θ in degrees.
θ = degrees, =
15. , Arcsine(sine inverse) of x, answer is in radians, 1>input value(x)>-1:
x = radians,
= radians degrees
16. cos(θ) = ?, Input the value of θ in degrees.
θ = degrees, =
17. , Arccosine(cos inverse) of x, answer is in radians, 1>input value(x)>-1:
x = radians,
= radians degrees
18. tan(θ) = ?, Input the value of θ in degrees, Remember tan(900) = ∞.
θ = degrees, =
19. , arctangent(tan inverse) of x, answer is in radians, ∞>input value(x)>0:
x = radians,
= radians degrees
