Calculus Solutions & Kiswahili Translation -- 2

I have two separate but straightforward needs that I’d like to bundle into one job.

First, I’m working through a set of Calculus problems and want clear, step-by-step solutions. These cover typical university-level topics—limits, differentiation, definite/indefinite integrals, and basic series work—nothing exotic, just sound mathematical reasoning presented in an easy-to-follow format. Please show each step so I can trace the logic and learn from it, and include any graphs or short code snippets (e.g., in Python or MATLAB) if they help illustrate the answer.

Second, I need a short text—about two pages—translated accurately into Kiswahili. It’s non-technical prose, so the emphasis is on natural, reader-friendly language rather than literal word-for-word phrasing. Maintain tone and nuance, and flag any idioms that don’t carry across cleanly so we can decide together on the best equivalent.

Deliverables
• A neatly formatted PDF or DOCX containing the worked Calculus solutions, with any supporting plots or code appended.
• A polished Kiswahili translation of the provided text, returned in the same layout as the original.

Acceptance criteria
• All calculus answers check out when re-worked or run through a CAS.
• Translation reads fluently to a native speaker, with meaning preserved.

If this matches your expertise in both mathematics and Kiswahili, I look forward to collaborating with you.
