I WISH BHAIYA REPLY DE Trigonometry Table: Angle 0° 30° 45° 60° 90° Sinθ 0 1/2 1/√2 √3/2 1 Cosθ 1 √3/2 1/√2 ½ 0 Tanθ 0 1/√3 1 √3 Undefined Cotθ Undefined √3 1 1/√3 0 Secθ 1 2/√3 √2 2 Undefined Cosecθ Undefined 2 √2 2/√3 1 Other Trigonometric formulas: sin(90° - θ) = cos θ cos(90° - θ) = sin θ tan(90° - θ) = cot θ cot(90° - θ) = tan θ sec(90° - θ) = cosecθ cosec(90° - θ) = secθ sin2θ + cos2 θ = 1 sec2 θ = 1 + tan2θ for 0° ≤ θ < 90° Cosec2 θ = 1 + cot2 θ for 0° ≤ θ ≤ 90° Get complete Trigonometry Formulas list here Circles Formulas For Class 10 Circumference of the circle = 2 π r Area of the circle = π r2 Area of the sector of angle θ = (θ/360) × π r2 Length of an arc of a sector of angle θ = (θ/360) × 2 π r (r = radius of the circle) Surface Area and Volumes Formulas For Class 10 The common formulas from the surface area and volumes chapter in 10th class include the following: Sphere Formulas Diameter of sphere 2r Surface area of sphere 4 π r2 Volume of Sphere 4/3 π r3 Cylinder Formulas Curved surface area of Cylinder 2 πrh Area of two circular bases 2 πr2 Total surface area of Cylinder Curved surface area of Cylinder + Area of Circular bases = 2 πrh + 2 πr2 Volume of Cylinder π r2 h Cone Formulas Slant height of cone l = √(r2 + h2) Curved surface area of cone πrl Total surface area of cone πr (l + r) Volume of cone ⅓ π r2 h Cuboid Formulas Perimeter of cuboid 4(l + b +h) Length of the longest diagonal of a cuboid √(l2 + b2 + h2) Total surface area of cuboid 2(l×b + b×h + l×h) Volume of Cuboid l × b × h Here, l = length, b = breadth and h = height. In case of Cube, put l = b = h = a, as cube all its sides of equal length, to find the surface area and volumes. took 1 hour PLS HELP ME TO REACH 5K subscriber TARGET:- WITHOUT POSTING VIDEO REACHING 5k BY HELPING 😀

Waaooww... Your way of teaching is just fab.. I'll get full marks in this topic...Thank you sir😊

Nice

Mai abhi class 12th Me hu or ye 10th class kaafi easy hai 😢 11 ki math ka ye sirf 1% hai too ready hoo jao 10th students 😂

Sir blue background se sentence nahi dik rahe ha

Very good nice super motivational inspiring 🎉🎉

Sir relation and function ke questions kara do

👍👍👍

Sir very good keep it up

Sir keep it up

Sir sample paper kab dalo ga

💀💀💀 great 👍

Super sir ❤

Very nice

Sir your videos are excellent, but I want to suggest you something that if you are uploading videos of class 12 maths then upload in a sequence because that will help the student in a better way like if uploading ITF then after that if you have to upload of differentiation upload differentiation first not integral and also make 2 playlist of 10th & 12th maths and add the videos there

Good sir ji

Nice 👍👍

Sie application me dout hai

Very nice explanation

Sir thankyou

I can already do that sir

Ok sir aapke motivation sun kar hogya vishwas

Happy Birthday sir 🎉

Ram ram sir ji🎉🎉🎉
