选项A语法不正确,需要加上花括号括起来的代码块;选项B的if语句中应该使用等于号(==)而不是不等于号(<>);选项C的语法正确,是if-else语句的形式;选项D的语法正确,当且仅当x小于y时,执行语句max=y。因此,正确的if语句形式是C。 考察的知识点是基本的条件语句。if语句需要满足判断条件,如果条件为真,...

If {eq}f(x,y) = e^{x^2 + xy + y^2} {/eq}, then find {eq}f_{yx} {/eq}. Partial Differentiation: If we have any multivariable function and we have to compute the derivative of this function with respect to one of the variables, the technique of differentiation that is...
If f(x)=xx then find f′(3) Finding Differentiation: Notice that f(x) is provided and we need to find f′(3). To find f′(3) we must need to find f′(x) first. Therefore with the help fo differentiation we will find f′(x) and then we will substitute x=3 to find f′...
