A mechanical engineer’s witty and relatable memes poking fun at trigonometric formulas have taken the internet by storm in April 2026. The series of humorous illustrations and captions, which creatively roast sin, cos, tan, and their real-life “uselessness” for most engineers, went massively viral after Paytm founder Vijay Shekhar Sharma shared the post on X, giving it even wider reach.
The memes, created by a mechanical engineering graduate (who chose to remain anonymous but is widely referred to as the “Trig-roasting Mech Engineer”), use simple drawings and desi humour to highlight how most engineering students memorise these formulas during exams but rarely use them in actual professional life.
What the Viral Memes Show
The series includes several panels:
- One meme shows a mechanical engineer happily working on a machine, with a thought bubble saying: “Thank God I never had to use sin θ = opposite/hypotenuse after college.”
- Another depicts a student struggling with a trigonometry problem in class, while the same person as an engineer is shown relaxing: “College: Learn trig or die. Job: Bro, just measure with a scale.”
- A particularly popular one shows a confused student surrounded by sin, cos, tan formulas, with the caption: “Mechanical Engineer after 4 years: Bhai, angle nikalne ke liye calculator hai na?”
The punchlines are light-hearted, self-deprecating, and instantly relatable to anyone who survived engineering mathematics.
Paytm Founder Vijay Shekhar Sharma Shares the Post
The memes gained explosive traction when Paytm founder and CEO Vijay Shekhar Sharma reposted them on X with a simple caption: “Too real 😂”
His share instantly amplified the reach, with thousands of likes, reposts, and comments from engineers, students, and even professors who admitted the truth behind the jokes.
Internet Reactions: Laughter & Nostalgia
The post received an overwhelming response:
- Engineers relating hard: “Finally someone said it. I passed trig by rote learning and never looked back.” “As a mechanical engineer, I confirm – we use scale, not sin cos tan.”
- Humorous takes: “Civil engineers laughing in the corner with their concrete mix ratios.” “ECE guys: At least we used complex numbers once.”
- Nostalgic & appreciative: “This brings back painful memories of engineering maths exams.” “Paytm founder sharing this is the cherry on top.”
Many teachers and professors also joined the conversation, some agreeing that while fundamentals are important, the heavy emphasis on rote learning of trig identities could be streamlined.
Why Trigonometry Feels “Useless” to Many Engineers
In most mechanical, civil, and even some electrical engineering roles, advanced trigonometric calculations are rarely done manually. Professionals rely on software (AutoCAD, SolidWorks, MATLAB, etc.), calculators, or pre-defined tables. This creates the common joke that “we studied trig for exams, not for the job.”
However, educators argue that learning trigonometry builds logical thinking, spatial awareness, and problem-solving skills that indirectly help in engineering.
