Arduino: 1.8.1 (Windows 10), Board: "Arduino/Genuino Uno" c:\program files (x86

I’m new in programming arduino. I need help to make out put from equation on 16x2 lcd screen
Help ASAP please.

void setup() {
float Angle4 = 0;

#include <LiquidCrystal.h>

LiquidCrystal lcd (13, 12, 11, 10, 9, 8);
#include <Keypad.h>

const byte ROWS = 4;

const byte COLS = 3;

char hexaKeys[ROWS][COLS] = {

{‘1’, ‘2’, ‘3’},

{‘4’, ‘5’, ‘6’},

{‘7’, ‘8’, ‘9’},

{’*’, ‘0’, ‘#’}
};

byte rowPins[ROWS] = {4, 3, 2, 1};

byte colPins[COLS] = {5, 6, 7};

Keypad customKeypad = Keypad(makeKeymap(hexaKeys), rowPins, colPins, ROWS, COLS);

lcd.println(“Kinematics proj.”);
delay(5000);
lcd.clear();
float R4 = 0;
for (float angle2 = 0; angle2 <= 3.14159; angle2 = angle2 + 0.2) {
int r1 = 500;
int r2 = 200;

Angle4 = atan2((r1 + (r2 * sin(angle2))), (r2 * cos(angle2)));

lcd.println(Angle4);
}
};

void loop() {
// put your main code here, to run repeatedly:

}

So what is the problem ?

Why is there a smiley in your code? Please ASAP read the sticky how to use the forum and apply.
