This is one of the best and light scientific calculators on play store.
Sample expressions
simple expression: 1+2
variable evaluation: pi
function evaluation: sin(0)
variable definition: a=3.5
function definition: f(x)=x^21
parentheses: (1x)^2
To enter an expression containing letters, such as sin(x), use the double arrow key on the basic keypad. It toggles opened/closed the letter keypad.
Predefined functions
Logarithms and power
sqrt(x): square root; x^0.5
cbrt(x): cube root; x^(1/3)
exp(x): exponential; e^x
log(x), ln(x): natural logarithm
log2(x), lb(x): binary logarithm
log10(x), lg(x): decimal logarithm
log(base,x): arbitrary base logarithm
Trigonometric  radians
sin(x), cos(x), tan(x)
asin(x), acos(x), atan(x)
Trigonometric  degrees
sind(x), cosd(x), tand(x)
asind(x), acosd(x), atand(x)
Hyperbolic
sinh(x), cosh(x), tanh(x)
asinh(x), acosh(x), atanh(x)
Other
gcd(x,y): greatest common divisor
comb(n,k): combinations
perm(n,k): permutations
min(x,y), max(x,y)
floor(x), ceil(x)
abs(x): absolute value
sign(x): signum
rnd(): random value from [0,1). rnd(max): random value from [0, max).
gamma(x): (x1)!
mod(x,y): modulo
Complex numbers
i or j is the complex base. Example:
i*i
(1+i)^2
e^(i*pi)
Operators
+  × ÷ basic arithmetic
^ power
% percent
! factorial
# modulo
√ square root
' first derivative
Tips
Parentheses: you may omit the leading or final parentheses, e.g. 1+2)(3+4 is valid.
Multiplication: you may omit the multiplication operator when unambiguous, e.g. 3π+2(1+2)
Expression continuation: starting a new expression with an operator autoinserts ans, the result of the last expression.
Clear: use the Enter key to quickly erase the whole input line.
Scientific e notation: 1e3 is 1000.
Angles in degrees instead of radians: use either sind(90) or sin(90deg).
Use trackball Up/Down to navigate the history.
Derivative
It is possible to compute the first derivative of a function with one argument using the prime notation: log'(5).
The prime mark (quote) must appear immediately after the name of the function, and must be followed by openparentheses.
The derivative may be plotted e.g. sqrt'(x).
To compute the derivative of an expression you must define the expression as a named function: E.g. f(x)=x^3+x^2+1, followed by f'(x).
Multi plot
To plot multiple functions on the same 2d graph, simply enter them on the same line separated by ";". E.g. x;x^2;2
Binary, octal, hexadecimal
You can enter values in binary, octal or hexadecimal by prefixing them with 0b, 0o or 0x respectivelly, such as:
binary: 0b1010
octal: 0o17
hexa: 0x100

Very usefull and unique Specially for technical students like me

Way too many privileges Why does this app demand ability to read phone state, access network, and get account data? Compare to sparse privileges required by ArityMOD. Quickly uninstalled.

Best one out there This app makes me realize that graphing calculators have no excuse for not being more awesome. It's simple and powerful.
