To evaluate the limit \( \lim _{h \rightarrow 0} \frac{(1+h)^{2}-1}{h} \), let's first simplify the expression. Expanding \( (1+h)^{2} \) gives \( 1 + 2h + h^{2} \). Therefore, the expression becomes: \[ \frac{(1 + 2h + h^{2}) - 1}{h} = \frac{2h + h^{2}}{h} = 2 + h \] Now, as \( h \) approaches 0, the limit simplifies to \( 2 + 0 = 2 \). Thus, \[ \lim _{h \rightarrow 0} \frac{(1+h)^{2}-1}{h} = 2. \] This result is a fundamental concept in calculus, representing the derivative of the function \( f(x) = x^{2} \) at the point \( x = 1 \). It's a key building block for understanding rates of change! Understanding limits like this is crucial to gaining a solid grasp of calculus concepts. You can explore them further through hands-on activities or interactive online courses that visualize these ideas, making learning both fun and effective.
