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 antilog_e(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
