Problem 1. (1 point) Evaluate the following expressions. Your answer must be an angle in radians and in the interval (-1/2.x]. Give exact answers; do not use decimal answers, You can enter the number a as pi . E.g. if the answer is 5/2 you could enter pi/2 or 1/2*pi. sin"'(!) =. sin= cos (-!)= _ Problem 2. (1 point) Evaluate the following expressions. Your answer must be an angle in radians and in the interval (-/2,/2). Give exact answers; do not use decimal answers. You can enter the number a as pi . E.g. if the answer is 5/2 you could enter pi/2 or 1/2*pi. tan (V3) =_ tan '( 3) =.. tan Problem 3. (1 paint) Rewrite the expression as an algebraic expresion in .c: tan(sinx)= Note: by algebraic . we mean that the answer is not allowed to use trig functions, or inverse trig fune- tions. It is allowed to involve polynomials, quotients. and roots. Problem 4. (1 point) If f(x) = 7xarcsin(x), find f(x). Find f'(0.3). Problem 5. (1 point) Find the first derivative of f(x) = 2sin"(13 ) Problem 6. (I point) If f(x) = 2arctan(4x). find /(x). Find f'
