Whenever I run this simple program below, i get the following error message: "Fatal Internal Error: Illegal size to spew_peek_op(read local)". What does it mean?? Please help.. void servo(char balloon) { const float left_b=400.0; const float (...) (25 years ago, 14-Dec-99, to lugnet.robotics.handyboard)

This polynomial approximation looks better: ArcSin(x) = Pi/2 - Sqrt(1-x)*(a(0) + a(1)*x + a(2)*x^2 + a(3)*x^3 + a(4)*x^4 + a(5)*x^5 + a(6)*x^6 + a(7)*x^7 ) where a(0) = 1.57079 63050 a(1) = -0.21459 88016 a(2) = 0.08897 89874 a(3) = -0.05017 43046 (...)

(...) You might give this a try (for -1 < x < 1): ArcSin(x) = x + a(1)*x^3 + a(2)*x^5 + a(3)*x^7 + ... etc. with a(1) = 0.1666666667 a(2) = 0.0750000000 a(3) = 0.0446428571 a(4) = 0.0303819444 a(5) = 0.0223721599 a(6) = 0.0173527644 a(7) = (...)

Hello, I would like to calculate an inverse sine (arcsin) function for one of my application. Does anyone know the algorithm of this trigonometric function? Thank you, J.M. Mongeau (25 years ago, 13-Dec-99, to lugnet.robotics.handyboard)

If you don't already have the L293D chips it would give you more current capability if you used the SN754410. It is pin compatible with the L293D and supplies 1A continuous versus 0.6A for the L293D, and they can be stacked just as Kam suggested for (...)
